Abstract

a new and convenient procedure has been developed for the preparation of sulfonamides from sodium sulfinates and amines with (n-C4H9)4NBr as bromine source and m-chloroperbenzoic acid as oxidant. This S–N bond formation reaction proceeds efficiently via sulfonyl bromides under neutral conditions to afford the corresponding sulfonamides in good yields at room temperature.
