摘要
A modified nickel catalyst used for stereo-differentiating reduction of carbonyl compounds is provided. The modified nickel catalyst is prepared by soaking a nickel catalyst in an aqueous modifying medium having dissolved therein at least one inorganic salt, such as sodium bromide or sodium chloride, and at least one optically active substance, such as optically active hydroxy acid. The modified nickel catalyst exhibits enhanced activity for stereo-differentiating reduction and causes little or no side reactions, and thus, brings about an extremely high yield of the reaction product.
