H2O2 in combination with SOCl2 proved to be it highly reactive reagent for the direct oxidative conversion of thiol derivatives to the corresponding sulfonyl chlorides with high purity through oxidative chlorination. Upon reaction with amines, the corresponding sulfonamides were obtained in excellent yields and in very short reaction times.
High yielding protocol for direct conversion of thiols to sulfonyl chlorides and sulfonamides
In this paper, a new method for oxidative chlorination of thiols to sulfonyl chlorides and sulfonamides using H2O2 in the presence of TMSCl is reported. The excellent yields, short reaction times, excellent efficiencies, low costs, and easy separation of products are the most important advantages of this method.[GRAPHICS].
