have been achieved via a palladium(0)‐catalyzed domino coupling reaction of (Z)‐β‐bromostyrenes with norbornenes in the presence of cesium carbonate and N,N‐dimethylformamide. The process involves a double Heck‐type procedure, two‐fold C(sp2)H activation and formation of two carbon‐carbon bonds. There are possibilities of diversified transformation for the domino coupling of (Z)‐β‐bromostyrenes with
多官能性分子,1,5-烯炔,已经实现通过钯(0)催化的(多米诺偶联反应Ž)-β-溴苯乙烯与在碳酸铯的存在和降冰片烯-N,N-二甲基甲酰胺。该过程涉及双重Heck型过程,两倍的C(sp 2)H活化和两个碳-碳键的形成。(Z)-β-溴苯乙烯与降冰片烯的多米诺偶联有多种转化的可能性,该过程通过精确调节反应条件成功地驱动到1,5-炔烃。
