Patent ID: 6855839

Claim:
A method to prepare a metal compound comprising reacting a neutral ligand with a compound represented by the formula M n X n where M is a group 3-14 metal, n is the oxidation state of M, and X is an anionic group in a non-coordinating or weakly coordinating solvent, at about 20 to about 100° C., then treating the mixture with an excess of an alkylating agent, then recovering the metal complex and wherein the neutral ligand is represented by the formula: where Y is a group 15 element, Z is a group 15 element, L is a group 15 or 16 element, R 1 and R 2 are independently a C 1 to C 0 hydrocarbon group, a heteroatom containing group, silicon, germanium, tin, lead, or phosphorus, R 1 and R 2 may be interconnected to each other, R 3 is absent, hydrogen, a group 14 atom containing group, a halogen, or a heteroatom containing group, R 4 and R 5 are independently an aryl group, a substituted aryl group, a cyclic alkyl group, a substituted cyclic alkyl group, or a multiple ring system, R 6 and R 7 are independently absent, hydrogen, halogen, a heteroatom, a hydrocarbyl group, or a heteroatom containing group.
