Abstract
The reaction of (Z)-2-amino-N‘-arylbenzamidines with both 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and 2,3,5,6-tetrachloro-1,4-benzoquinone have been studied. The reactions were carried at room temperature overnight in dry ethyl acetate and proceed via a charge transfer complexe to give dibenzo[b,e][1,4]diazepine derivatives in 35–44% yield. Benzodiazepine derivatives have anti-inflammatory, antiviral, antimicrobial, antileukaemic, antiplatelet, anticonvulsant, antianxiety, antidepressive and antitumour activities. The products were fully characterised according to their spectral analyses.
