Reactions of phosphonitrilic trimer with difunctional/polyfunctional nukleophilic reagents and spectroscopic analysis of the derived products

In this work, we carried out a substancial investigation of the effect of temperature, base and the solvent system on the reactivity of the reactions of cyclotriphosphazene with difunctional nucleophilic reagents. We found that temperature, use of the solvent and the base effect the product types and the relative yields of the products, particularly on ansa compound, single-, double- and tri-bino-type precursors. The reactivity of N3P3CI6 (1) with difunctional nucleophilic reagents, in an extention of the research on the nucleophilic substitution reactions of cylochlorotriphosphazene with linear aliphatic diamines, NH2-(CH2)n-NH2 (n=3 and 6 ) are surveyed. We subjected the reactions of the hexachloride, to a systematic reinvestigation with aliphtic propane-l,3- (2) and hexane-1,6-diamines (3) and we obtained almost all structural types: spiro, ansa and bridged derivatives: mono-spiro, N3P3Cl4[HN(CH2)3NH] (4); its mono-ansa isomer, N3P3Cl4[HN(CH2)3NH] (5): mono-ansa, N3P3Cl2[HN(CH2)6NH]2 (6) türevi; dispiro, N3P3Cl2[HN(CH2)3NH]2 (7); their spiro-ansa isomers, N3P3Cl2[HN(CH2)3NH]2 (8), N3P3Cl2[HN(CH2)6NH]2 (9); tris-spiro, N3P3[HN(CH2)3NH]3 (10); and intermolecular condensation derivatives; single-, double-, and triple-bridged respectively, N3P3Cl5[HN(CH2)3NH]N3P3Cl5 (11), N3P3Cl5[HN(CH2)6NH]N3P3Cl5 (12); N3P3Cl4[HN(CH2)6NH]2N3P3Cl4 (13); and N3P3Cl3[HN(CH2)6NH]2N3P3Cl3 (14) compounds. The structures of the derived compounds were illuminated by elemental analysis, MS, TLC-MS, 31P and 1H NMR spectral data.
