Abstract
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.
