合成了一系列聚醚取代的噻唑鎓离子液体并用作Stetter反应的催化剂。离子液体是一种温控相分离催化（TPSC）系统，因为它们具有临界溶液温度（CST）和在甲苯-庚烷中的逆温度依赖性溶解度的特性。结果表明，新型TPSC系统表现出较高的回收效率，并为环境友好的Stetter反应提供了潜在的途径。
A series of polyether-substituted thiazolium ionic liquids have been synthesized and used as catalysts in the Stetter reaction. The ionic liquids are a thermoregulated phase-separable catalysis (TPSC) system, because they possess the properties of critical solution temperature (CST) and inverse temperature-dependent solubility in toluene–heptane. The results showed that the novel TPSC system exhibits high recycling efficiency, and provides a potential route for a environmentally benign Stetter reaction.
