Alkyl radicals are obtained by photocatalytic oxidation of readily prepared or commercially available zinc sulfinates. The convenient benzylation and alkylation of a variety of electron-poor olefins triggered by the iridium(III) complex 6 Ir[dF(CF3)ppy]2(dtbbpy)PF6 as photocatalyst is described. Moreover, it is shown that zinc sulfinates can be used for facile nonradical sulfonylation reactions with
通过容易制备或可商购的亚磺酸锌的光催化氧化获得烷基。描述了铱(III)配合物6 Ir [dF(CF 3)ppy] 2(dtbbpy)PF 6作为光催化剂引发的各种电子贫乏烯烃的便捷苄基化和烷基化。此外,已表明亚磺酸锌可用于具有高度亲电性的迈克尔受体的容易的非自由基磺酰化反应。
