Aryloxypentachlorocyclotriphosphazenes and their properties

Compounds of the general formula N3P3Cl5(OC6H4-4-R), where R = H, F, Cl, CH3, or OCH3, have been prepared under anhydrous conditions. The cyclic trimers were characterized by IR spectroscopy, mass spectrometry and elemental analysis. IR data indicated that both chloro and aryloxy groups are bonded to the phosphorus atoms of the N3P3 ring. The mass spectra of the various compounds were found to be similar with the loss of the aryloxy group the dominant fragmentation process. Each spectrum exhibited a molecular ion peak and no evidence was found for contamination by other partially substituted aryloxychlorocyclotriphosphazenes. Elemental analysis further verified the general formula N3P3Cl5(OC6H4-4-R) for each of the compounds.
