Unexpected Substitution Reactions of 1,3-Dithietane-1,1,3,3-Tetraoxide (Disulphene)

Abstract

1,3-Dithietane-1,1,3,3-tetraoxide (“disulphene”) is a versatile reagent for the synthesis of sulphenes and sulphines¹. Upon investigating silylation reactions of disulphene (1) an unexpected O-silylation yielding a sulphoxoniumylide was found². The synthesis of more stable sulphoxoniumylides will be reported³.
