1-Benzyl-N-tolyl-1,2,3-triazole-4-carboxamide was accessed via rearrangement of N-benzyl-1-tolyl-1,2,3-triazole-4-carboxamide. It is shown that by boiling in various solvents an equilibrium between isomeric triazoles and diazomalondiamides is established, and that the equilibrium is shifted toward 1-benzyl-1,2,3-triazole. The two isomeric triazoles are shown to undergo alkylation reactions. For 5-hydroxy-1-tolyl-1
通过N-苄基-1-甲苯基1,2,3-三唑-4-羧酰胺的重排来获得1-苄基-N-甲苯基1,2,3-三唑-4-羧酰胺。结果表明,通过在各种溶剂中沸腾,在异构的三唑和重氮丙二酰胺之间建立了平衡,并且该平衡向1-苄基-1,2,3-三唑转移。显示两种异构体三唑进行烷基化反应。对于5-羟基-1-甲苯基1,2,3-三唑,烷基化发生在杂环的3位,形成中离子性三唑-5-醇酸酯,而对于1-苄基-5-羟基-1,2, 3-三唑烷基化导致形成5-烷氧基衍生物。
