Reaction of 5-aryltetrazoles with N,N′-bis(p-tolyl)terephthalimidoyl dichloride under conditions of phase-transfer catalysis yields isomeric N-imidoyltetrazoles whose thermolysis results in formation of 3H-1,3,4-benzotriazepines. The latter are hydrolyzed by the action of hydrochloric acid to afford terephthalic acid and the corresponding aminobenzophenone.
