Visible light-mediated radical alkenylation of benzylsulfonium salts was achieved by means of fac-Ir(ppy)3 as a photocatalyst, giving allylbenzenes as products. A variety of functional groups, such as halogen, ester, and cyano, were well tolerated in this transformation. Starting benzylsulfonium salts could be readily prepared from benzyl alcohols by an acid-mediated substitution, increasing the synthetic
借助fac-Ir(ppy)3作为光催化剂实现苄基salts盐的可见光介导的自由基烯基化,生成烯丙基苯。在这种转化过程中,对各种官能团(如卤素,酯和氰基)具有很好的耐受性。起始的苄基salts盐可以很容易地由苯甲醇通过酸介导的取代来制备,从而增加了这种转化的合成效用。
