    • A method for producing a desired optically active carboxylic acid with a high optical purity, wherein a complex catalyst used can be recovered and reused as an aqueous solution. The method contains the step of subjecting an &agr;,&bgr; -unsaturated carboxylic acid in water or a mixed solvent of water and a water-insoluble organic solvent in the presence of a sulfonated BINAP—Ru complex represented by the formula [3]: [RuX(arene){(SO?3#191M)?2#191-BINAP}]X [3]wherein X represents a chlorine atom, a bromine atom or an iodine atom, arene represents a benzene or an alkyl-substituted benzene, M represents an alkaline metal atom, and BINAP represents 2,2′-bis(diphenylphosphine)-1,1′-binaphthyl to an asymmetric hydrogenation. The sulfonated BINAP—Ru complex can be recycled.
    • 一种制备具有高光学纯度的所需光学活性羧酸的方法,其中可以回收使用的复合催化剂并将其再次用作水溶液。 该方法包括在由式[3]表示的磺化BINAP-Ru络合物的存在下使α,β-不饱和羧酸在水或水和水不溶性有机溶剂的混合溶剂中进行的步骤:[RuX (芳烃){(SO 3#191M)2#191-BINAP}] X [3]其中X表示氯原子,溴原子或碘原子,芳烃表示苯或烷基取代的苯,M 代表碱金属原子,BINAP代表2,2'-双(二苯基膦)-1,1'-联萘与不对称氢化反应。 磺化的BINAP-Ru络合物可以回收利用。
