EFFICIENT PHOSPHOROUS-SULFUR BOND REDUCTION IN BICYCLIC THIAPHOSPHORANES WITH TRI-n-BUTYLTIN HYDRIDE

Abstract
High yield photolytic reduction of a series of thiaphosphoranes Z p SR to give Z p H
with UV-light-induced tri-n-butyltin hydride through phosphoranyl radical Z p is
described. This reaction is inhibited by a-methylstyrene and initiated by a radical
initiator such as azobisisobutyronitrile
