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.
