4,5-Dihydro-1,3,4-benzotriazepines were obtained in good yields by intramolecular thermal cyclization of arylazoanils with methyl or ethyl groups in the ortho positions of the aromatic ring on the imine nitrogen.
Non Conventional Syntheses of Heterocyclic Compounds. 2. Synthesis of 1H-4,5-Dihydro-1,3,4-Benzotriazepine Derivatives

Arylazoanils carrying aromatic methyl or ethyl groups in the position ortho to the imine function thermally cyclize to give 1H-4,5-dihydro-1,3,4-benzotriazepine derivatives in fairly good yields.A study of the effect of the substituents on both the aryl rings is reported.The reaction is interpreted as an internal oxo-reduction process.
