The present invention provides an optically active cobalt (II) complex suitable for the production of optically active alcohols useful as synthetic raw materials for synthetic materials such as pharmaceuticals and agricultural chemicals and functional materials such as liquid crystals. An optically active cobalt (II) complex represented by formula (a). [In the formula, R 1 and R 2 are different groups, each of which is a hydrogen atom or an aryl group, and may have a substituent, and two R 1 or two R 2 may be R 3 , R 4 and R 5 may be bonded to each other to form a ring, and each of R 3 , R 4 and R 5 is a hydrogen atom, a linear or branched alkyl group or aryl group, an acyl group or an alkoxycarbonyl group. You may have. Embedded image [Selection] Figure 2 |
