Recently in this laboratory convenient method for synthesis of 2-[(2-p-chlorophenyliminoimino-6-substitutedamino)-1,3,5-dithiazino]imino-11-(piprazine-1-yl)dibenzo[b,f] [1,4]oxazepines [VIIIB(a-h)] was developed. The interactions of 2-[ p-chlorophenylimino-2,4-dithiabiureto]-11-(piperazin-1-yl)dibenzo[b,f] [1,4] oxazepine [VB(a)] with various isocyanodichloride (VIIa-f) in 50% acetone-ethanol medium were carried out on water bath to synthesized [VB(a-f)] respectively. The structures of synthesized compounds were justified on the basis of chemical characteristics, elemental analysis and spectral studies.
