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.

Keywords: 4-Amino-5-alkyl-4H-1,2,4-triazole-3-thione, thiocarbohydrazide, long-chain aliphatic carboxylic acids, Schiff bases
