Here we report a copper-catalyzed protocol for the synthesis of α-chloroketones from aromatic alkenes including electron-deficient olefins under visible-light irradiation. Preliminary mechanistic studies show that the peroxo Cu(II) species is the key intermediate and hydroperoxyl (HOO⋅) and chlorine (Cl⋅) radicals can be generated by ligand-to-metal charge transfer (LMCT).
在此，我们报道了一种在可见光照射下，由包括缺电子烯烃在内的芳香烯烃合成α-氯代酮的铜催化方法。初步机理研究表明，过氧铜（II）物种是关键中间体，通过配体到金属的电荷转移（LMCT）可生成氢过氧自由基（HOO⋅）和氯自由基（Cl⋅）。
