There is provided novel bimetallic salen catalyst. The bimetallic salen catalyst is represented by SaI(M1 )M2 (X) n, wherein Sal represents a chiral salen ligand, M1 and M2 represent each inde- pendently transition metal ions coordinated with the salen ligand, X represents anion that binds to M2 to form a salt, n has a value corresponding to oxidation number of M2. The bimetallic salen catalyst provides chiral compounds in a high optical purity by kinetic chiral resolution. The bimetallic salen catalyst exhibits sufficiently improved reactivity and activity, compared to conventional salen catalysts obtained from 1: 1 coordination complex between one salen ligand and one transition metal ion. Therefore, the bimetallic salen catalyst can be suitably used for the synthesis of chiral compounds through kinetic chiral resolution.
