Abstract

Some new 4-aryl imino -3-tert-butyl-l,3,4,5-tetrahydro-2H-1,3,5-benzotriazepine-2 thione (Va-e) were synthesized via 2-aryl imino –N-4-tertbutylimino-4,5-dihydro-3,1,5- benzothiadiazepine (IVa-e) by the condensation of 1-(2-aminophenyl)-3-phenyl thioureas (IIa-e) with tert-butyl
imino isocyanodichloride. The 1-(2-aminophenyl)-3-phenyl thioureas (IIa-e) were obtained by the treatment of o-phenylene diamine and aryl
isothiocyanates. The synthesized compounds 4-aryl imino -3-tert-butyl-l,3,4,5-tetrahydro-2H-1,3,5-benzotriazepine-2-thione (Va-e) were
successfully de-tertbutylated into respective 4-arylimino-1,3,4,5-tetrahydro-2H-1,3,5-benzotriazepine-2-thiones (VIa-e).

Keywords: 1, 3, 5-Benzotriazepine-2-thiones, 3,1,5 benzothiadiazepine, O-phenylene diamine, Aryl isothiocyanate, T-butyl imino isocyanodichloride.
