Thermolysis of N-imidoyltetrazoles generated under conditions of phase-transfer catalysis from 5-aryltetrazoles and N-(2-naphthyl)benzimidoyl chloride yields 3H-naphtho[2,1-e][1,2,4]triazepines, and acid hydrolysis of the latter leads to formation of 3-arylbenz[e]indazoles. Acid hydrolysis of 3H-naphtho[1,2-e]-[1,2,4]triazepine gives the corresponding amino ketone.
在相转移催化条件下,由 5-芳基四氮唑和 N-(2-萘基)苯亚甲酰氯生成的 N-亚胺酰基四氮唑发生热分解,得到 3H-萘并[2,1-e][1,2,4]三氮杂卓,后者发生酸水解,生成 3-芳基苯并[e]吲唑。酸水解 3H-萘并[1,2-e][1,2,4]三氮杂卓可得到相应的氨基酮。
