Biphilic insertions into a sulphur–oxygen bond by tervalent phosphorus compound

Abstract

Tervalent phosphorus compounds often react with ethyl benzenesulphenate to give ethoxythiophenoxyphosphoranes; these can react with another mole of ethyl benzenesulphenate to give ethoxyphosphoranes and diphenyl disulphide, or they can decompose by ionic pathways.
