A Pd-catalyzed three-component reaction of N-tosylhydrazone, terminalalkyne, and aryl halide follows a mechanism involving a sequence of Pd carbene migratory insertion-transmetalation-reductive elimination, leading to the formation of one sp(2)-sp(3) C-C bond and one sp-sp(3) C-C bond.
Pd 催化的 N-甲苯磺酰腙、末端炔烃和芳基卤化物的三组分反应遵循涉及 Pd 卡宾迁移插入-金属转移-还原消除序列的机制,导致形成一个 sp(2)-sp(3) ) CC 键和一个 sp-sp(3) CC 键。
