An efficient Mizoroki–Heck/amination cascade reaction of o-dihaloarenes with allylamines has been developed using nickel and IPr carbene ligand as catalyst. This protocol enables the synthesis of a broad range of substituted indoles by a cascade process, from readily available starting materials. Mechanistic studies suggest that the Mizoroki–Heck reaction occurred first under IPr-nickel catalysis.
使用镍和IPr卡宾配体作为催化剂,开发了邻二卤代芳烃与烯丙胺的有效Mizoroki-Heck /胺化级联反应。该方案能够通过级联方法从容易获得的起始原料合成各种取代的吲哚。机理研究表明,Mzoroki-Heck反应首先在IPr-镍催化下发生。
