dc.description.abstract |
In an extension of the research on the nucleophilic substitution reactions of hexachlorocyclotriphosphazene (1) with linear aliphatic primary diamines, NH2-(CH2)(n) -NH2 (n = 3, 5, 6 and 8) are surveyed. In the presence of pyridine, NaH and in excess of the used amine as base, at 0 degrees C and room temperature, we subjected the reactions of 1, to a systematic reinvestigation with aliphatic propane-1,3-, pentane-1,5-, hexane-1,6- and octane-1,8-diamines (2, 3, 4 and 5 respectively) and we isolated a total of 18 compounds which include examples of all four structural types (open chain, spiro, ansa and the bino derivatives). The novel synthesized open chain (6), mono-ansa (8a), spiro-ansa (10), single-bridged (12a), double-bridged (13a) and tri-bridged (14a) cyclophosphazene derivatives are reported for the first time. The synthesized compounds are characterized by elemental analysis, MS, FT-IR, H-1 and P-31 NMR spectroscopy. Spectroscopic data, product types and the relative yields are compared with those of the previously reported cyclophosphazene derivatives derived from di-functional nucleophilic reagents.
