Abstract
Interaction of hexachlorocyclodiphosphazanes (Ia-f) and 2,4-dithio-2,4-dichlorocyclodi-phosphazane derivatives (IIa-f) with diphenyl-(4-dimethyl amino phenyl) methanol (III) and 2,3-dihydroxy naphthalene (IV) has been described. The structures of the cyclodiphosphazane derivatives (Va-I) and (VIa-I) were proposed on the basis of microanalytical data, IR, Mass spectra, 1HNMR and 31P NMR spectra. The biological activity of these compounds was studied on different microorganisms.
