enables the direct allylation of strong aliphatic C–H bonds with simple allylic chlorides. The method relies on a cooperative interaction of two metal catalysts in which the decatungstate anion acts as a hydrogen-atom abstractor generating a nucleophilic carbon-centered radical that engages in an SH2′ reaction with an activated allylic π-olefin–copper complex. Because of this dual catalysis, the protocol
在这里,我们报告了一种光催化方法,该方法能够用简单的烯丙基氯化物直接烯丙基化强脂肪族 C-H 键。该方法依赖于两种金属催化剂的协同作用,其中十钨酸盐阴离子作为氢原子吸收剂产生亲核碳中心自由基,该自由基与活化的烯丙基π-烯烃-铜络合物发生S H 2' 反应。由于这种双重催化作用,该协议允许在温和条件下在短反应时间内对一系列化学原料和天然产物进行功能化。
