A lanthanide‐catalyzed sequential insertion of CN and CC into an NH bond is presented. The convenient reaction, which proceeds under mild conditions, is an efficient method for preparing 1,2,4‐trisubstituted imidazoles directly from readily available propargylamines and nitriles.
CN和CC的镧系元素催化的顺序插入到一个N H键被呈现。在温和的条件下进行的便捷反应是直接从容易获得的炔丙基胺和腈制备1,2,4-三取代的咪唑的有效方法。
