Abstract

By the reaction of N, N'-thiocarbonyl diimidazole with diazomethane, diazoacetic ethylester, phenyl diazoketone and 4-nitrophenyl diazomethyl ketone catalysed by tertiary amines, 5- substituted 2-(1-imidazolyl)-1, 3, 4-thiadiazoles were prepared, by the action of N, N'- thiocarbonyl diimidazole with azoimide, trimethylsilyl azide and thiophosgene 5-(1- imidazolyl)-1, 2, 3, 4-thiatriazole was synthesised. The structure of compounds prepared ...
