Preparation of 5,5-Dicyano- and 5-Cyano-5-ethoxycarbonyl-5,5-dihydro-3,7-diphenyl-4H-1,2-diazepines and Their Halogenations

5,5-Dicyano- and 5-cyano-5-ethoxycarbonyl-5,6-dihydro-3,7-diphenyl-4H-1,2-diazepines were prepared by the condensation of α-bromoacetophenone azine with malonitrile and ethyl cyanoacetate in the presence of sodium ethoxide, respectively.Halogenations of t
