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.
