Patent ID: 8039655

Claim:
Complex having the formula where R 1 , R 2 , and R 4 are the same or different, and are each a hydrogen atom, a halogen atom, a fluorocarbon group, a heterocyclic compound residue, an oxygen-containing group, a nitrogen-containing group, a boron-containing group, a sulfur-containing group, a phosphorus-containing group, a carbon-containing group, or a silicon-containing group, where R 3 is a hydrogen atom, a halogen atom, a fluorocarbon group, a heterocyclic compound residue, an oxygen-containing group, a nitrogen-containing group, a boron-containing group, a sulfur-containing group, a phosphorus-containing group, or a methyl group, a silicon-containing group, and two or more of R 1 , R 2 , R 3 , and R 4 may be bonded to each other to form a ring or rings; where R 7 and R 8 are different and neither is a hydrogen, and are a halogen atom, a fluorocarbon group, a heterocyclic compound residue, an aromatic group, an oxygen-containing group, a nitrogen-containing group, a boron-containing group, a sulfur-containing group, a phosphorus-containing group, a carbon-containing group or a silicon-containing group, and they may be bonded to each other to form a ring or rings; n is an integer from 1-3; m is an integer from 0-4; M is a group 3-11 transition metal; L is a linking bridge that is a carbon-containing group, a silicon-containing group, or a boron-containing group; Y is a hydrogen atom, a halogen atom, an oxygen-containing group, a sulfur-containing group, a nitrogen-containing group, a boron-containing group, an aluminum-containing group, a phosphorus-containing group, a halogen-containing group, a heterocyclic compound residue, a carbon-containing group, a silicon-containing group, a germanium-containing group or a tin-containing group, and when m is 2, 3 or 4, plural groups Y may be the same or different and may be bonded to each other to form a ring; and the bonds between M and N and L and N are coordinative, covalent, or ionic, and the case is excluded where R 1 is sec-phenethyl, R 3 is Me, R 7 is Me, R 8 is Ph, L is derived from an α-diketone, M is Ni, n is 1, Y m is Br 2 and all stereogenic centers of the sec-phenethyl groups are of the same absolute configuration.
