synthesis of a novel cyclotriphosphazene by using xanthydrol oxygen containing ligand

A new derivative of cyclotriphosphazene with xanthydrol as the oxygen-containing ligand was synthesized. firstly hexaclorocyclotriphosphazene was obtained hexaclorocyclotriphosphazene from ammonium chloride and phosphorus pentachloride reaction and then the deprotonated xanthydrol was reacted with hexaclorocyclotriphosphazene in the ratio of 6:1 in dry toluene as the solvent. all of the cl atoms were substituted with hydroxyl groups of ligand to give a new product with (np (c14h10o) 2)3 formula. this product was identified by a series of spectroscopic techniques including ftir, ^31p nmr, ^13c nmr, ^1h nmr and mass spectroscopy. analyses were performed to confirm the formation of the designed product and structure.
