本文报道了使用亲核三氟甲基化试剂从硫脲合成N，N '-二烷基-2-三氟甲基硫代咪唑盐。研究了咪唑盐在固-液相条件下作为相转移催化剂对活性亚甲基化合物烷基化等反应的催化活性。
We herein report the synthesis of N,N′-dialkyl-2-trifluoromethylthioimidazolium salts from thioureas using nucleophilic trifluoromethylating reagents. The activity of imidazolium salts as phase-transfer catalysts under solid–liquid phase conditions was investigated for reactions such as the alkylation of active methylene compounds.
