Thioethers bearing an optically active secondary alcohol were desulfurized with Raney nickel — sodium hypophosphite — acetate buffer system to give optically active alcohols without racemization in high yields. This Raney nickel combination system exhibited a unique desulfurization of benzylthio or phenylthio group in the presence of benzyl ether.
用阮内镍-次磷酸钠-乙酸盐缓冲体系对带有旋光性仲醇的硫醚进行脱硫,制得旋光性醇,而无需高产率的外消旋化。该阮内镍组合系统在苄基醚存在下表现出独特的苄硫基或苯硫基脱硫。
