Recently, ionic liquids (ILs) have emerged as reaction media for many heterocyclic syntheses. 13 We report herein a novel and efficient procedure for the synthesis of 3,5-diaryl-1,2,4-thiadiazoles using aryl nitriles as substrate and using (NH 4 ) 2 S, 2,4,6-trichloro -1,3,5-triazine (TCT) and dimethylsulfoxide in 1-butyl-3-methylimidazolium bromide (Scheme 1). ... To the best of our knowledge, there is no report on the thioamidation-oxidation- ...
