[en] Two oxime-cyclophosphazenes were prepared from the hexakis(4-formylphenoxy)cyclotriphosphazene and hexakis(4-acetylphenoxy)cyclotriphosphazene. The reactions of these oximes with ethyl bromide, allyl bromide, propanoyl chloride, and acriloyl chloride were studied. Hexasubstituted compounds were obtained from the reactions of hexakis{4-[(hydroxyimino)methyl]phenoxy}cyclotriphosphazene with ethyl bromide, allyl bromide, and propanoyl chloride, however, the oxime groups on 3 rearranged to nitrile in the reaction of 3 with acriloyl chloride. Hexasubstituted compounds were also obtained from the reactions of hexakis{4-[(1)-N-hydroxyethaneimidoyl]phenoxy}cyclotriphosphazene with allyl bromide and propanoyl chloride. Tetra- and penta-substituted products were obtained from the reactions of 9 with ethyl bromide and acriloyl chloride, respectively. All products were generally obtained in high yields. The structures of the compounds were defined by elemental analysis, IR, ¹H, ¹³C, and ³¹P NMR spectroscopy. (author)
