N2 - The triphenylsiloxy-substituted cyclotriphosphazenes, N3P3ClS5OSiPh3 gem-N3P3cl4(OSiPh3)2, N 3P3(OSiPh3) 6, and N3P3(OPh) 5OSiPh3, have been prepared. The synthesis of gem-N3P3Cl4(OSiPh3)2 involves the reaction of (NPCl2)3 with Ph3SiONa to fortn the intermediates gem-N3P3Cl4(OSiPh3)2(ONa) and gem-N3P3Cl4(ONa)2, which yield gem-N3P3Cl4(OSiPh3)2 when treated with Ph3SiCl. The compounds N3P3Cl5OSiPh3 and N3P3(OSiPh3)3 are formed by the condensation reactions of N3P3Cl5OBun and N3P3OBun)6, respectively, with Ph3iCl. The compound N3P3(OPh)5OSiPh3 is synthesized by the reaction between N3P3(OPh)5Cl and Et3SiONa to first give the intermediate N3P3(OPh) 5ONa, which yields N3P3(OPh) 3OSiPh3 when reacted with Ph3SiCl. The structural characterization and properties of these compounds are discussed. The crystal and molecular structure of gem-N3P3Cl4(OSiPh3)2 has been investigated by single-crystal X-ray diffraction techniques. The crystals are monoclinic with the space group P21/c with a = 16.850(8), b = 12.829(4), c = 18.505(15) Å, and β= 101.00(6)° with V = 3927 Å3and Z = 4.
