Disclosed is a novel optically active dinickel complex. Also disclosed is a method for producing a novel optically active amine by an asymmetric Mannich reaction using the optically active dinickel complex as a catalyst. Specifically disclosed is a novel optically active dinickel complex represented by the formula (I) or (I') below. Also specifically disclosed is a novel method for producing an optically active amine by an asymmetric Mannich reaction using the optically active dinickel complex as a catalyst. [chemical formula 1] (I) (I') (In the formulae, R0, R1, R4, R5, R6 and R7 respectively represent a hydrogen atom, a halogen atom, a C1-10 alkyl group, a C1-10 alkoxy group or the like; and R2 and R3 form a naphthalene ring together with the benzene ring to which R2 and R3 are bonded to.) |
