Substitution reaction of hexachlorocyclotriphosphazene with trimethylaluminum
The reaction of hexachlorocyclotriphosphazene with trimethylaluminum yields the fully substituted hexamethylcyclotriphosphazene and a ring-opened linear phosphazene salt. The substitution pathway that yields the fully substituted cyclic product was determined by monitoring the reactions of several methylchlorocyclotriphosphazenes with trimethylaluminum with the use of gas chromatography and /sup 31/P NMR spectroscopy. The reaction was found to proceed via both geminal and nongeminal substitution pathways, depending on the species undergoing substitution. The degree of ring opening that occurred was observed to decrease with increasing methyl substitution of the phosphazene ring. The new products prepared were characterized by /sup 1/H, /sup 13/C, and /sup 31/P NMR spectroscopy, infrared spectroscopy, mass spectrometry, and elemental analysis. 27 refs., 6 figs., 1 tab.
