sulfonyl‐containing ammonium‐based Brønstedacidionic liquid was prepared and used as a liquid heterogeneous catalyst for organic reactions. The unique macroscopic phase heterogeneity of the IL in the reaction system not only ensures an excellent catalytic activity of the IL catalyst but also avoids the use of organic reaction solvents. The catalyst system is applicable for a wide range of reactions.

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。
