Abstract

The combination of H₂O₂ and SOCl₂ is a highly reactive reagent for the direct oxidative conversion of thiol derivatives to the corresponding sulfonyl chlorides through oxidative chlorination. Upon reaction with amines, the corresponding sulfonamides were obtained in excellent yields in very short reaction times.
