 Title    Synthesis of Hexahydro-bisfbenzo-dipyrazolones, benzo-diazepinone] and Dithiopyrimidoquinazolinetetrone  
 Abstract    A new series of hexahydro-bis-benzodipyrazolones (2a-e) were obtained by the inter-action of 1 with hydrazines. These pyrazolones underwent coupling reaction with different diazonium salts to give 7a-g. Compound 1 when treated with acid hydrazides gave 3 a, b, and when subjected to Japp-Klingemann reaction in alkaline medium gave 6a-e. The hexahydro-bis-benzodiazepine (8), and dithiopyrimidoquinazolinetetrone (10) were obtained by the interaction of 1 with o-phenylenediamine and thiourea respectively.
