are different separately selected from halogen atom or amino; Z is halogen atom; R2 R3 R4 R5 R6 R7 and R8 are defined respectively as mentioned before; R1 are defined as mentioned before but R1?H. According to the above preparation method treatment of intermediate ? with intermediate ? at the presence of base gives compounds ?-a of general formula I (R1=H) which react with Z-R1 to give compounds ?-b of general formula I (R1?H). The proper base mentioned above may be selected from potassium hydroxide sodium hydroxide sodium carbonate potassium carbonate sodium bicarbonate triethylamine pyridine sodium methoxide sodium ethoxide sodium hydride potassium tert-butoxide or sodium tert-butoxide and so on. The reaction can be carried out in proper solvent and the proper solvent mentioned may be selected from tetrahydrofuran acetonitrile toluene xylene benzene DMF N-methylpyrrolidone DMSO acetone or butanone and so on. The proper reaction temperature is from room temperature to boiling point of solvent generally is 20-100°C. The reaction time is in the range of 30 minutes to 20 hours generally is 1-10 hours. Intermediates ? are commercially available or prepared according to the known methods such as referring to Indian Journal of Chemistry Section B: Organic Chemistry Including Medicinal Chemistry 45B(4) 972-975 2006; Tetrahedron Letters 44(21) 4085-4088 2003; PL174903 etc. Intermediate ? can be prepared according to the known methods such as referring to JP2003292476 US2010160695 etc. The compounds of general formula I can also be prepared by other methods for example the nitration of substituted diphenylamine intermediate (general formula ?) can give compounds of general formula I with NO2 group referring to US4041172 and so on. Wherein: R1 R2 R4 R5 R6 R7 and R8 are defined respectively as mentioned before; R3 is selected from H or NO2. The nitration of compounds of general formula I in which at least one of R4 R6 or R8 is H can add one or two NO2 groups to these compounds of general formula I.

Therefore a further technical scheme of the present invention relates to fungicidal compositions containing one or more compounds having general formula I as active ingredient and acceptable carrier in agriculture the weight percentage of the active ingredient in the compositions is 0.5-90%. Compositions can be used in the form of dry powders wettable powders emulsifiable concentrates microemulsions pastes granulates solutions suspensions etc..The selection of the type of compositions depends on the specific application. The compositions are prepared in the known method for example by diluting or dissolving the active substance with a solvent medium and/or a solid diluent optionally in the presence of surface-active agents. Solid diluents or carriers which can be used are for example: silica kaolin bentonite talc diatomite dolomite calcium carbonate magnesia chalk clays synthetic silicates attapulgite sepiolite. Liquid diluents which can be used are for example besides water aromatic organic solvents (xylols or mixtures of alkylbenzols chlorobenzene etc.) paraffins (petroleum fractions) alcohols (methanol propanol butanol octanol glycerin etc.) esters (ethyl acetate isobutyl acetate etc.) ketones (cyclohexanone acetone acetophenone isophorone ethylamylketone etc.) amides (N N-dimethylformamide N-methylpyrrolidone etc.). Surface-active agents which can be used are salts of sodium calcium triethylamine or triethanolamine of alkylsulfonates alkylarylsulfonates polyethoxylated alkylphenols polyethoxylated esters of sorbitol ligninsulfonates etc. The compositions can also contain special additives for particular purposes for example adhesion agents such as Arabic gum polyvinyl alcohol polyvinyl-pyrrolidone etc. The concentration of active ingredient in the above compositions can vary within a wide range depending on the active compound the applications for which they are destined the environmental conditions and the type of adopted formulation. In general the concentration of active ingredient ranges from 1% to 90% preferably from 5% to 50%. If required other active ingredients being compatible with the compounds having general formula I can be added to the compositions such as other acaricides/insecticides fungicides plant growth regulators antibiotics herbicides fertilizers.
