The α‐regioselective conjugate addition of allyl groups to activated alkenes is a poorly explored area of research. Herein, we report an α‐adduct and (E )‐isomer selective conjugate addition of allylsilanes to activated alkenes by visible‐light photoredox catalysis. The reaction involves allylic radicals that can be generated from allylsilanes through a photoinduced single‐electron transfer mechanism.

可见光光氧化还原催化的烯基到活化烯烃的α-区域选择性共轭加成。

烯丙基在活化烯烃上的α-区域选择性共轭加成是一个研究不足的领域。在这里，我们报道了通过可见光光氧化还原催化将烯丙基硅烷与活化烯烃进行α-加合物和（E）-异构体选择性共轭加成反应。该反应涉及烯丙基自由基，该烯丙基自由基可以通过光诱导的单电子转移机理由烯丙基硅烷产生。
