Abstract
It was found by 31P NMR spectroscopy and paper chromatography that amidochloro-cyclo-triphosphazenes N3P3Cl4(NH2)2 and N3P3Cl5NH2 undergo hydrolysis in acidic, neutral, and alkaline medium with preservation of their cyclic skeleton to give triphosphazane anions (NHPO2)33-. As found spectroscopically, the hydrolysis of N3P3Cl4(NH2)2 in acidic medium leads initially to formation of an intermediate of the composition N3P3(OH)4(NH2)2, which speaks for the preferential hydrolytic cleavage of P-Cl bonds compared to exogenic P-NH2 bonds in the molecule of this compoud.
