Thiocarbohydrazide reacts with two molar proportions of diarylcarbodi-imides in dimethylformamide or methanol to yield 5-arylamino-4-(NN′-diarylguanidino)-3-mercapto-1,2,4-triazoles, together with some 4-aryl-3-aryl-amino-5-mercapto- and 4-aryl-3,5-di(arylamino)-1,2,4-triazoles. The structure of the main-products follows from the identity of their 3-S-alkylthio-derivatives with compounds synthesised
与二甲基甲酰胺或甲醇diarylcarbodi酰亚胺的二摩尔比例的氨基硫脲进行反应,得到5-芳基氨基-4-(NN '-diarylguanidino)-3-巯基-1,2,4-三唑,与某些4-芳基-3-一起芳基-氨基-5-巯基和4-芳基-3,5-二(芳基氨基)-1,2,4-三唑。主要产物的结构来自其3 - S-烷硫基衍生物与由等分子量的二芳基碳二亚胺和3-烷硫基-4-氨基-5-芳基氨基-1,2,4-明确合成的化合物的同一性三唑。后者的结构通过将该系列的选定成员脱氨基为3-苯胺基-5-甲硫基1,2,4-三唑而证实。
