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.
合成了基于 1,2,4- 三唑骨架的新型化合物。硫代羧酰肼与长链脂肪族羧酸反应生成了一类 4-氨基-5-烷基-4H-1,2,4-三唑-3-硫酮,然后在催化剂存在或不存在的情况下,在加热和微波介质中获得了希夫碱。它们的化学结构是通过元素分析和设备光谱方法测定的。
