An efficient copper(II) catalyzed sulfonyation of aryl halides has been achieved using TosMIC (p-toluenesulfonylmethyl isocyanide) as a sulfonylating agent. This newly developed sulfonylation approach provides an easy access for the synthesis of diaryl sulfones from aryl bromides, iodides and boronic acids with TosMIC under neutral conditions. This method is useful for the sulfonylation of aryl boronic
