| Abstract |
Pyridyldiamido transition metal complexes are disclosed for use in alkene polymerization. The ligands are tridentate with an NNN configuration. The general formula is: wherein: M is a Group 3,4, 5, 6, 7, 8, 9,10, 11 or 12 metal; Z is -(R14)pC-C(R15)q-, where R14 and R15 are independently selected from the group consisting of hydrogen, hydrocarbyls and substituted hydrocarbyls (preferably alkyl), and wherein adjacent R14 and R15 groups may be joined to form an aromatic or saturated, substituted or unsubstituted hydrocarbyl ring, where the ring has 5, 6, 7, or 8 ring carbon atoms and where substitutions on the ring can join to form additional rings, p is 1 or 2, and , q is 1 or 2; R1 and R11 are independently selected from the group consisting of hydrocarbyls, substituted hydrocarbyls, (such as alkyl, aryl, heteroaryl) and silyl groups; R2 and R10 are each, independently, -E(R12)(R13)- with E being carbon, silicon, or germanium, and each R12 and R13 being independently selected from the group consisting of hydrogen, hydrocarbyls (e.g. alkyl and aryl), substituted hydrocarbyls (e.g. heteroaryl), alkoxy, silyl, amino, aryloxy, halogen, and phosphino, R12 and R13 may be joined to form a saturated, substituted or unsubstituted hydrocarbyl ring, where the ring has 4, 5, 6, or 7 ring carbon atoms and where substitutions on the ring can join to form additional rings, or R12 and R13 may be joined to form a saturated heterocyclic ring, or a saturated substituted heterocyclic ring where substitutions on the ring can join to form additional rings; R3, R4, and R5 are independently selected from the group consisting of hydrogen, hydrocarbyls (e.g. alkyl and aryl), substituted hydrocarbyls (e.g. heteroaryl), alkoxy, aryloxy, halogen, amino, and silyl, and wherein adjacent R groups (R3 & R4, and /or R4 & R5) may be joined to form a substituted or unsubstituted hydrocarbyl or heterocyclic ring, where the ring has 5, 6, 7, or 8 rmg atoms and where substitutions on the ring can join to form additional rings; L is an anionic leaving group, where the L groups may be the same or different and any two L groups may be linked to form a dianionic leaving group; n is0, 1,2, 3, or 4; L' is neutral Lewis base; and w is 0, 1,2, 3 or 4. The invention shows processes and intermediates for making these complexes. |
