(57) Abstract: A novel optically active bidentate phosphine ligand palladium complex that can be used for the production of optically active β-hydroxyketones is provided. SOLUTION: Formula (I) or formula (II) [Wherein Y − means an anion pair capable of forming a salt, X − Is {In the formula, R 1 represents a hydrogen atom, a C 1-6 alkyl group, a C 1-6 alkoxy group, a cyano group, a nitro group, a halogen atom, a phenyl group or the like. m means 1 or 2. m is 2 In the case of, two R 1 may be the same or different. ｝ And A and B are independently a phenyl group or a cyclohexyl group (the phenyl group and the cyclohexyl group are R 2 (Wherein R 2 has the same meaning as R 1 ), which may be optionally substituted}, and the optically active bidentate phosphine ligand palladium complex. |
