A synergistic catalytic method combining photoredox catalysis, hydrogen‐atom transfer, and proton‐reduction catalysis for the dehydrogenative silylation of alkenes was developed. With this approach, a highly concise route to substituted allylsilanes has been achieved under very mild reaction conditions without using oxidants. This transformation features good to excellent yields, operational simplicity
开发了一种光催化氧化还原,氢原子转移和质子还原催化相结合的烯烃脱氢甲硅烷基化的协同催化方法。通过这种方法,在非常温和的反应条件下,无需使用氧化剂,即可获得高度简洁的取代烯丙基硅烷的制备方法。这种转变具有良好到极好的产量,操作简单和高原子经济性的特点。基于控制实验,提出了一种可能的反应机理。
