Microwave irradiated synthesis of Schiff bases of 4-(arylideneamino)-5-alkyl-2,4- dihydro-1,2,4-triazole-3-thione containing 1,2,4-triazole segment

Abstract

Novel compounds based on the 1,2,4-triazole skeleton were synthesized. A class of 4-amino-5-alkyl-4H-1,2,4-triazole-3- thione created by reaction of thiocarbohydrazide with long-chain aliphatic carboxylic acids, and then the Schiff bases were obtained in the media of heat and microwave waves, in the presence and the absence of a catalyst. Their chemical structures were assayed by elemental analysis, also device spectroscopic methods.
