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
烯丙基砜是通过铜催化的无配体区域选择性磺酰化反应从容易获得的 α-甲基苯乙烯衍生物和磺酰氯合成的。这种氧化还原中性协议还具有低成本的金属催化剂、广泛的底物范围、良好的官能团耐受性,并且可以平滑地放大到克级。烯丙基砜产品可用于多种自由基偶联反应。
