Allyl sulfones are synthesized via Cu-catalyzed ligand-free regioselective sulfonylation reaction from easily obtained α-methylstyrene derivatives and sulfonyl chlorides. This redox-neutral protocol also features a low-cost metal catalyst, broad substrate scope, good functional group tolerance and could be smoothly amplified to a gram scale. The allylic sulfone products can be used in diverse radical
