Deoxygenation of sulphoxides to sulphides with trichlorophosphane

Abstract

An efficient route to deoxygenation of sulphoxides to sulphides with PCl₃ under mild reaction condition was developed. PCl₃ was used as a reducing agent for the first time to convert sulphoxides to sulphides. The mild conditions, use of cheap and readily available reagent, and broad substrate scope render it a useful strategy for preparing sulphides.
