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.
