A facile and efficient indium-catalyzed sulfonylation of amines allows the synthesis of a wide range of sulfonamides in excellent yields. The method showed a generality for substrates including less nucleophilic and sterically hindered anilines, and it is also applicable for preparing sulfonic esters from sulfonyl chlorides and alcohols.
