1-Alkoxycarbonylbenzotriazoles on thermolysis lose carbon dioxide; the decarboxylation is accompanied by the formation of a mixture of 1- and 2-alkylbenzotriazoles, with the N-1 isomer predominating over the N-2 isomer in all cases. A cross-over experiment, in which heating equimolar amounts of 1-benzyloxycarbonylbenzotriazole and 1-(4-methylbenzyloxycarbonyl)-5,6-dimethylbenzotriazole gave almost
1-烷氧基羰基苯并三唑在热解过程中会损失二氧化碳;脱羧反应伴随着1-烷基苯并三唑和2-烷基苯并三唑的混合物的形成,在所有情况下,N -1异构体均高于N -2异构体。交叉实验中,加热等摩尔量的1-苄氧基羰基苯并三唑和1-(4-甲基苄氧基羰基)-5,6-二甲基苯并三唑几乎产生了所有交换产物,该实验支持所提出的分子间机理,用于该脱羧反应和形成1-和2-烷基苯并三唑。1-苯氧基羰基苯并三唑未观察到脱羧。
