Title:

METAL COMPLEX COMPRISING HETEROATOM AND TWO METALS

Document Type and Number:

Japanese Patent JP3822844

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a heterobimetallic transition metal complex utilizable as a homogeneous catalyst, etc.
SOLUTION: The metal complex represented by formula (1) (wherein, M1 denotes a tri-, a tetra- or a pentavalent transition metal; M2 denotes a transition metal; X denotes a hydrogen atom, a halogen atom, a 1-20C hydrocarbon group or an alkoxy group or an amino group: n is an integer of 1-3; R1 denotes a 1-20C hydrocarbon group or a hydrocarbon group having a silicon atom; R2 denotes a 1-20C hydrocarbon group; a hydrocarbon group having a silicon atom or an alkoxy group or an amino group; Z denotes an oxygen atom, a sulfur atom or an NR (wherein, R denotes an alkyl group) when Z is present; L denotes a halogen atom, a 1-20C hydrocarbon group or an akoxy group, a carbonyl group, phosphines, isonitriles, ethers or sulfides; and m denotes an integer of 2-4) or a dimer thereof is obtained. The metal complex is used as a catalyst for polymerizing olefins.
