Abstract

A mild and efficient catalytic method for Friedel–Crafts sulfonylation of arenes to the corresponding sulfones using a catalytic amount of reusable solid acid and arene-or alkanesulfonyl chlorides, sulfonic anhydrides and sulfonic acids as sulfonylating agents is described. Solid acids enable formation of a sulfone by the reaction of a sulfonic acid and an arene for the first time. In pursuit of the development of the best catalytic system, various ...
