Thermolysis of both 1- and 2-N-arylbenzimidoyl-5-dimethylaminotetrazoles [(7) or (8)] generates nitrile imines (9), which cyclise to yield either 1,2,4-triazoles (10) or 3H-1,3,4-benzotriazepines (12), depending on the nature of the N-aryl group and on conditions.
两个1-热分解和2- Ñ -arylbenzimidoyl -5- dimethylaminotetrazoles [(7)或(8)]产生的腈
亚胺(9),得到环化其中任一
1,2,4-三唑(10)或3 ħ - 1,3,4-苯并三氮杂卓(12),取决于N-芳基的性质和条件。
