The first iron‐catalyzed 1,2‐difunctionalization of styrenes and conjugated alkenes with silanes and either N or C, using an oxidative radical strategy, is described. Employing FeCl2 and di‐tert‐butyl peroxide allows divergent alkene 1,2‐difunctionalizations, including 1,2‐aminosilylation, 1,2‐arylsilylation, and 1,2‐alkylsilylation, which rely on a wide range of nucleophiles, namely, amines, amides
描述了使用氧化自由基策略的首次铁催化的苯乙烯和共轭烯烃与硅烷以及N或C的1,2-双官能化。使用FeCl 2和二叔丁基过氧化物可以实现不同的烯烃1,2-双官能化,包括1,2-氨基甲硅烷基化,1,2-芳基甲硅烷基化和1,2-烷基甲硅烷基化,它们依赖于广泛的亲核试剂,即胺,酰胺,吲哚,吡咯和1,3-二羰基化合物,因此为生产各种含硅烷烃提供了强大的平台。
