摘要

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.
