Abstract

Several chlorine/oxygen exchange reactions of [PCl₂N]₃ were investigated with the goal of forming [PON]₃, a precursor to PON materials. The reaction of MeSO₃H and Et₃N with hexachlorocyclotriphosphazene ([PCl₂N]₃) has been claimed to produce a [PON]₃ single molecule. This reaction could not be reproduced. Only partially oxygenated phosphazenes have been obtained. Similarly, in the reaction of [PCl₂N]₃ and dimethylformamide (DMF) both partial and full oxygenation occurs. Stoichiometry appears to be crucial in determining the species that is produced in both reactions. These products were characterized by multinuclear NMR spectroscopy.
