Patent ID: 7964744

Claim:
A method for producing a ruthenium complex comprising the step of reacting a ruthenium compound represented by general formula (1): [RuX(L)(PP)]X (1), wherein Ru represents a ruthenium atom, X represents a halogen atom, L represents an arene, and PP represents an optically active bisphosphine, with a carboxylate salt represented by general formula (2): R 1 CO 2 M (2), wherein M represents a monovalent cation, and R 1 represents a group selected from the group consisting of alkyl groups, haloalkyl groups, phenyl groups optionally having a substituent(s), 1-aminoalkyl groups and 1-amino-1-phenylalkyl groups, to produce a ruthenium complex represented by general formula (3): Ru(OCOR 1 ) 2 (PP) (3), wherein R 1 represents a group selected from the group consisting of alkyl groups, haloalkyl groups, phenyl groups optionally having a substituent(s), 1-aminoalkyl groups and 1-amino-1-phenylalkyl groups, and PP represents an optically active bisphosphine.
