TITLE ARTHROPODiCIDAL ANTHRANILAMIDES
BACKGROUND OF THE INVENTION
This invention relates to certain anthranilamides, their iV-oxides, agriculturally suitable
salts and compositions, and methods of their use for control of invertebrate _Bgsis_sxich-aff
arthropods in both agronomic and nonagronomic environments. The control of invertebrate pests such as arthropods is extremely important in achieving high crop efficiency. Damage by invertebrate pests to growing and stored agronomic crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of invertebrate pests in forestry, greenhouse crops, ornamentals,, nursery crops, stored food and fiber products, livestock, household, and public and animal health is also important. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different modes of action.

DETAILS OF THE INVENTION In the above recitations, the term "alkyl", used either alone or in compound words such
15 as "alkylthio" or "haloalkyl" includes straight-chain or branched alkyl, such as, methyl, ethyl, /z-propyl, z"-propyl, or the different butyl isomers. One skilled in the art will appreciate that not all nitrogen containing heterocycles can form iV-oxides since the nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen containing heterocycles which can form iV-oxides. One skilled in the art will also
20 recognize that tertiary amines can form iV-oxides. Synthetic methods for the preparation of iV-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and 7rc-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as f-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethydioxirane.
25 These methods for the preparation of JV-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive"Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J.

wherein R6 is C1-C4 alkyL
In this method, a hydrazine compound of Formula 18 is contacted with a compound of Formula 25 (a fumarate ester or maleate ester or a mixture thereof may be used) in the presence of a base and a solvent. The base is typically a metal alkoxide salt, such as sodium methoxide, potassium methoxide, sodium ethoxide, potassium ethoxide, potassium tert-butoxi&e, lithium tert-bntoxide, and the like. Greater than 0.5 equivalents of base versus the compound of Formula 18 should be used, preferably between 0.9 and 1.3 equivalents. Greater than 1.0 equivalents of the compound of Formula 25 should be used, preferably between 1.0 to 1.3 equivalents. Polar protic and polar aprotic organic solvents can be used, such as alcohols, acetonitrile, tetrahydrofuran, iV^-dimethylformamide, dimethyl sulfoxide and the like. Preferred solvents are alcohols such as methanol and ethanol. It is especially preferred that the alcohol be the same as that making up the fumarate or maleate ester and the alkoxide base. The reaction is typically conducted by mixing the compound of Formula 18 and the base in the solvent. The mixture can be heated or cooled to a desired temperature and the compound of Formula 25 added over a period of time. Typically reaction temperatures are between 0 °C and the boiling point of the solvent used. The reaction may be conducted under greater than atmospheric pressure in order to increase the boiling point of the solvent. Temperatures between about 30 and 90 °C are generally preferred. The addition time can be as quick as heat transfer allows. Typical addition times are between 1 minute and 2 hours. Optimum reaction temperature and addition time vary depending upon the identities of the compounds of Formula 18 and Formula 25. After addition, the reaction mixture can be held for a time at the reaction temperature. Depending upon the reaction temperature, the required hold time may be from 0 to 2 hours. Typical hold times are 10 to 60 minutes. The reaction mass then can be acidified by adding an organic acid, such as acetic acid and the like, or an inorganic acid, such as hydrochloric acid, sulfuric acid and the like. Depending on the reaction conditions and the means of isolation, the -C02R6 function on the compound of Formula 23 may be hydrolyzed to -C02H; for example, the presence of water in the reaction mixture can promote such hydrolysis. If the carboxylic acid (-C02H) is formed, it can be converted back to -CO2R6 wherein R6 is C1-C4 alkyl using esterification methods well-known in the art. The desired product, a compound of

Formula 23, can be isolated by methods known to those skilled in the art, such as
crystallization, extraction or distillation.
It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula 1 may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, T. W. Greene and P. G. M. Wuts, Protective Groups In Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula 1. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula 1.
It is believed that one skilled in the art using the preceding description can utilize the present invention to its fullest extent. The following Examples are, therefore, to be construed as merely illustrative, and not limiting of the disclosure in any way whatsoever. Steps in the following Examples illustrate a procedure for each step in an overall synthetic transformation, and the starting material for each step may not have necessarily been prepared by a particular preparative run whose procedure is described in other Examples or Steps.

Formulation/Utility
Compounds of this invention will generally be used as a formulation or composition 5 with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions,
10 emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active
15 ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.
The formulations will typically contain effective amounts of active ingredient, diluent
20 and surfactant within the following approximate ranges that add up to 100 percent by weight.

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey. Typical liquid diluents are described in Marsden, Solvents Giride, 2nd Ed., Interscience, New York, 1950. McCutcheon"s Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foanij caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity.
Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, AyV-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxy-ethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, 7\yV-dimethylformamide, dimethyl sulfoxide, JV-alkylpyrrolidone, ethylene glycol, polypropylene glycol, propylene carbonate, dibasic esters, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, rang, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy-4-methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol, benzyl and tetrahydrofurfuryl alcohol.
Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. 3,060,084. Granules and pellets can be prepared by spraying the active-material upon preformed granular carriers or by agglomeration techniques.

Compounds of this invention are characterized by favorable metabolic and/or soil residual patterns and exhibit activity controlling a spectrum of agronomic and non-agronomic invertebrate pests. (In the context of this disclosure "invertebrate pest control" means inhibition of invertebrate pest development (including mortality) that causes significant reduction in feeding or other injury or damage caused by the pest; related expressions are defined analogously.) As referred to in this disclosure, the term "invertebrate pest" includes arthropods, gastropods and nematodes of economic importance as pests. The term "arthropod" includes insects, mites, spiders, scorpions, centipedes, millipedes, pill bugs and symphylans. The term "gastropod" includes snails, slugs and other Stylommatophora. The term "nematode" includes all of the helminths, such as: roundwonns, heartworms, and phytophagous nematodes (Nematoda), flukes (Tematoda), Acanthocephala, and tapeworms (Cestoda). Those skilled in the art will recognize that not all compounds are equally effective against all pests. Compounds of this invention display actmty against economically important agronomic and nonagronomic pests. The term "agronomic" refers to the production of field crops such as for food and fiber and includes the growth of cereal crops (e.g., wheat, oats, barley, rye, rice, maize), soybeans, vegetable crops (e.g., lettuce, cabbage, tomatoes, beans), potatoes, sweet potatoes, grapes, cotton, and tree fruits (e.g., pome fruits, stone fruits and citrus fruits). The term "nonagronomic" refers to other horticultural (e.g., forest, greenhouse, nursery or ornamental plants not grown in a field), public (human) and animal health, domestic and commercial structure, household, and stored product applications or pests. For reason of invertebrate pest control spectrum and economic importance, protection (from damage or injury caused by invertebrate pests) of agronomic crops. of cotton, maize, soybeans, rice, vegetable crops, potato, sweet potato, grapes and tree fruit by controlling invertebrate pests are preferred embodiments of the invention. Agronomic or nonagronomic pests include larvae of the order Lepidoptera, such as armyworms, cutworms, loopers, and heliothines in the family Noctuidae (e.g., fall armyworm {Spodoptera fiigiperda J. E. Smith), beet arrnyworrn (Spodoptera exigua Htibner), black cutworm (Agrotis ipsilon Hufnagel), cabbage looper (Trichoplusia ni Hxibner), tobacco budworm (Heliothis virescens Fabricius)); borers, casebearers, webworms, coneworms, cabbageworms and skeletonizers from the family Pyralidae (e.g., European corn borer (Ostrinia nubilalis Htibner), navel orangeworm (Amyelois transnsitella Walker), corn root webworm {Crambus caliginosellus Clemens), sod webworm (Herpetogramma

In certain instances, combinations with other invertebrate pest control compounds or agents having a similar spectrum of control but a different mode of action will be particularly advantageous for resistance management. Thus, compositions of the present invention can further comprise a biologically effective amount of at least one additional invertebrate pest control compound or agent having a similar spectrum of control but a different mode of action. Contacting a plant genetically modified to express a plant protection compound (e.g., protein) or the locus of the plant with a biologically effective amount of a compound of invention can also provide a broader spectrum of plant protection and be advantageous for resistance management.
Invertebrate pests are controlled in agronomic and nonagronomic applications by applying one or more of the compounds of this invention, in an effective amount, to the environment of the pests including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Thus, the present invention further comprises a method for controlling an invertebrate pest, comprising contacting the invertebrate pest or its environment with a biologically effective amount of one or more of the compounds of the invention, or with a composition comprising at least one such compound, or with a composition comprising at least one such compound and an effective amount of at least one additional biologically active compound or agent. Examples of suitable compositions comprising a compound of the invention and an effective amount of at least one additional biologically active compound or agent include granular compositions wherein the additional biologically active compound or agent is present on the same granule as the compound of the invention or on granules separate from those of the compound of this invention.
A preferred method of contact is by spraying. Alternatively, a granular composition comprising a compound of the invention can be applied to the plant foliage or the soil. Compounds of this invention are also effectively delivered through plant uptake by contacting the plant with a composition comprising a compound of this invention applied as a soil drench of a liquid formulation, a granular formulation to the soil, a nursery box

treatment or a dip of transplants. Compounds are also effective by topical application of a composition comprising a compound of this invention to the locus of infestation, Other methods of contact include application of a compound or a composition of the invention by direct and residual sprays, aerial sprays, gels, seed coatings, microencapsulations, systemic 5 uptake, baits, eartags, boluses, foggers, fumigants, aerosols, dusts and many others. The compounds of this invention may also be impregnated into materials for fabricating invertebrate control devices (e.g., insect netting).
The compounds of this invention can be incorporated into baits that are consumed by the invertebrates or within devices such as traps and the like. Granules or baits comprising 10 between 0.01-5% active ingredient, 0.05-10% moisture retaining agent(s) and 40-99% vegetable flour are effective in controlling soil insects at very low application rates, particularly at doses of active ingredient that are lethal by ingestion rather than by direct contact.
The compounds of this invention can be applied in their pure state, but most often 15 application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, other solvents, and synergists such as piperonyl 20 butoxide often enhance compound efficacy.
The rate of application required for effective control (i.e. "biologically effective amount") will depend on such factors as the species of invertebrate to be controlled, the pest"s life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal 25 circumstances, application rates of about 0.01 to 2 kg of active ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.0001 kg/hectare may be sufficient or as much as 8 kg/hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required. 30 One skilled in the art can easily determine the biologically effective amount necessary for the desired level of invertebrate pest control.
The following Tests in the Biological Examples of the Invention demonstrate the control efficacy of compounds of this invention on specific pests. "Control efficacy" represents inhibition of arthropod development (including mortality) that causes significantly 35 reduced feeding. The pest control protection afforded by the compounds is not limited, however, to these species. See Index Table A for compound descriptions.

BIOLOGICAL EXAMPLES OF THE INVENTION
TESTA For evaluating control of diamondback moth {Plutella xylostella) the test unit consisted of a small open container with a 12-14-day-old radish plant inside. This was pre-infested 5 with 10-15 neonate larvae on a piece of insect diet by use of a core sampler to remove a plug from a sheet of hardened insect diet having many larvae growing on it and transfer the plug containing larvae and diet to the test unit. The larvae moved onto the test plant as the ditt plug dried out.
Test compounds were formulated using a solution containing 10% acetone, 90% water 10 and 300 ppm X-77® Spreader Lo-Foam Formula non-ionic surfactant containing alkylarylpolyoxyethylene, free fatty acids, glycols and isopropanol (Loveland Industries, Inc.), unless otherwise indicated. The formulated compounds were applied in 1 mL of liquid through a SUJ2 atomizer nozzle with 1/8 JJ custom body (Spraying Systems Co.) positioned 1.27 cm (0.5 inches) above the top of each test unit. All experimental compounds in this 15 screen were sprayed at 50 ppm and replicated three times. After spraying of the formulated test compound, each test unit was allowed to dry for 1 hour and then a black, screened cap was placed on top. The test units were held for 6 days in a growth chamber at 25 °C and 70% relative humidity. Plant feeding damage was then visually assessed.
Of the compounds tested, the following provided excellent levels of plant protection
20 (10% or less feeding damage): 1, 2, 3, 4, 5, 6, 7, 8, 9, 1=0, 11, 12, 13, 14, 15, 16, 17, 18, 19,

second, third and fourth treatments, 35-50 first instar Heliothis virescens larvae were brushed on each plant with paintbrushes and placed on the terminal area, squares^ and bolls. Five days after the last infestation with larvae the plants were rated for damage. Of the compounds tested, the following provided excellent levels of plant protection at 10 ppm 5 (10% or less feeding damage): 16.
Of the compounds tested, the following also provided excellent protection of squares and bolls at 10 ppm, with no feeding or minimal sepal damage: 16.
TEST I Test I followed an alternative protocol for evaluating soil systemic control of tobacco
10 budworm (Heliothis virescens). Cotton plants were grown in sassafras soil in 15-cm pots under greenhouse conditions. When the plants reached square stage (bud formation on the plant) the soil surface was treated with the test compounds.
Test compounds were formulated in 0.25 mL of acetone and then diluted with water. Ten mL of treatment solution containing 3 mg of compound was added to the soil surface of
15 each pot. The plants were watered the next day and each day following as needed. At 1, 2 and 4 days after treatment, leaves were excised for evaluation. Two sets of leaves were selected from each plant: upper leaves at approximately second node from terminal and with area greater than 25 cm2 and lower leaves at approximately third node from bottom and with area greater than 25 cm2. The excised leaves were cut into 3 cm x 2 cm sections and placed
20 into test trays made of high-impact styrene consisting of sixteen contiguous wells, each 6 cm wide, 4 cm long and 3 cm deep, with a clear plastic lid molded so that it locked into each well by friction. Solidified agar was placed into the bottom of each well to maintain moisture for plant material. One second instar tobacco budworm was placed into each well with plant material; cells were sealed and held at 25 °C and provided with 16 hours of light
25 per day. For leaves excised at 1, 2, and 4 days mortality was observed 4 days after treatment with one second instar todacco budworm.
Of the compounds tested, the following compounds provided excellent levels of mortality (greater than 70% mortality) on upper leaves excised at 4 days after treatment at the test rate: 2,27,33.
30 TEST J
For evaluating soil systemic control of fall armyworm (Spodoptera frugiperda), corn (maize) plants (Eioneer #3394) were grown in small pots for 5 days until they were at least 4 cm tall and the first leaf was Unfurling.
Test compounds were dissolved in 0.25 mL of acetone and diluted with water to
35 provide solutions of 1, 10, 50 and 200 ppm. 1 mL of the test solution was applied by pipette
to the surface of the soil in each pot, with eight plants for each compound/rate. The pots
were covered and held at 25 °C with 16 hours of light per day. The plants were watered the

next day and each day following as needed. After 6 days, the plant matter above the first leaf was excised and cut into 3-cm lengths. Each test unit was a high-impact styrene tray (Supplier: Cleaxpack Company, 11610 Copenhagen Court, Franklin Park, IL 60131) consisting of sixteen contiguous wells each 6 cm wide, 4 cm long and 3 cm deep, with a 5 clear plastic lid molded so.that it locked into each well by friction. Solidified agar (2 to 4 mL) was placed onto the bottom of each well to maintain moisture in the wells during the test. Each 3-cm length -of corn plant matter was placed into a tray such that the plant matter was contained within two wells. One second-instar fall armyworm (Spodoptera frugiperda) larva was placed in each well, the tray was covered and then the test units were held at 25 °C
10 with 16 hours of light per day. Mortality was observed after four days.
LC90 concentrations (test compound concentrations giving 90% kill of the larvae) were calculated based on probit analysis (log linear regression) using a general linearized model (GLIM) of the SAS statistical computer analysis product of SAS Institute (Cary, NC, U.S.A.). Of the compounds tested, the following provided excellent levels of mortality, with
15 LC90 values of 10 ppm or less: 1,2, 4,9, 11,12, 14, 16, 20, 22, 24, 31, 32, 33, 34.
TEST K For evaluating control of Colorado potato beetle (Leptinotarsa decemlineate), 5 mg samples of the test compounds were dissolved in 1 mL of acetone. This solution was then diluted to 100 mL total volume using an aqueous 500 ppm solution of Ortho X-77™ 20 surfactant. Serial dilutions were made to obtain 50 mL of 10 ppm concentration.
The diluted solutions of the test compounds were sprayed to run-off on three-week-old
potato or tomato plants. The plants were placed on a rotating turntable sprayer (10 rpm).
Test solutions were applied using a flat fan air-assisted nozzle (Spraying Systems 122440) at
10 psi (69 kPa). After each treated plant had dried, leaves were excised from the treated
25 plant. The leaves were cut into pieces, which were placed singly into 5.5 cm-by-3.5 cm cells
of a sixteen-cell plastic tray. Each cell contained a 2.5-cm square of moistened
chromatography paper to prevent desiccation. One second instar larvae was placed in each
cell. At three days after infestation the total number of dead Colorado potato beetles was
recorded.
30 Of the compounds tested, the following resulted in at least 90% mortality at 10 ppm:
2,4,27,33,34,41,61,85.
TESTL For evaluating control of boll weevil (Anthonomus g. grandis), samples of the test compounds were dissolved in 1 mL of acetone. This solution was then diluted to 100 mL 35 total volume using an aqueous 500 ppm solution of Ortho X-77™ surfactant. Serial dilutions were made to obtain 50 mL of 50 ppm concentration.
