Abstract:
A compound of the formula (V) wherein:R1 is hydrocarbyl or substituted hydrocarbyl; R2 is hydrogen, hydrocarbyl or substituted hydrocarbyl; with the proviso that R1 and R2 taken together may be ortho-arylene or substituted ortho-arylene; R3 is hydrogen, hydrocarbyl, substituted hydrocarbyl or a functional group, provided that when R1 and R2 taken together are ortho-arylene or substituted ortho-arylene, R3 may form a fused ring system therewith; R4 and R5 are each independently hydrogen, hydrocarbyl, or substituted hydrocarbyl, provided that R4 and R5 taken together may form a ring, and further provided that when Q is oxygen or sulfur R5 is not present; Q is nitrogen, oxygen, phosphorous or sulfur; Z is a bridging group of the formula (II) or (III) R6 is hydrogen, hydrocarbyl or substituted hydrocarbyl, or R3 and R6 together may form a ring; R7 is hydrogen, hydrocarbyl or substituted hydrocarbyl, provided that R3, R6 and R7 together may form an aromatic ring, or R6 and R7 taken together may form a ring; R8 is hydrogen, hydrocarbyl or substituted hydrocarbyl; R9 is hydrogen, hydrocarbyl, substituted hydrocarbyl, or R4 and R9 taken together may be part of a double bond to an imino nitrogen atom, or R8 and R9 taken together may form a ring, or R4, R5, R8 and R9 taken together may form an aromatic ring, or R4 and R9 taken together may form a ring, or R4, R8 and R9 taken together may form a ring R10, R11, R12 and R13 are each independently hydrogen, hydrocarbyl or substituted hydrocarbyl, or R10, R11, R12 and R13 taken together are ortho-arylene; R14 is hydrogen, hydrocarbyl or substituted hydrocarbyl; R4 and R15 together are part of a double bond to an imino nitrogen atom; M is selected from the group consisting of Ni, Pd, Fe, Cr, V, Ti, Zr and Hf; m is an integer equal to the valence of M minus 1; p is 0 or 1; and each L3 is independently a monodentate monoanionic ligand, and L4 is a monodentate neutral ligand or an empty coordination site, or an L3 and L4 taken together are a monoanionic bidentate ligand.
