Synthesis and characterizations of some oo and no substituted spiro, ansa and bino phosphazene derivatives

In this study, at first stage, six ligands were synthesised from the condensation reactions of 2-amino-3-hydroxypyridin and 4-aminobenzylamin with salicylaldehyde, 5-chlorosalicylaldehyde and 5-bromosalicylaldehyde, respectively (L1-L6). Then, by reducing three of them (L4-L6) new three ligands were synthesised (L7-L9). All ligands were reacted with hexachlorocyclotriphosphazene, N3P3Cl6, and cyclic ansa- (B1-B3), spiro- (B4-B6) and bino- (B7-B9). type phosphazene compounds were obtained. Structures of all molecules have been explained by FT-IR, 1H-, 13C- 31P-NMR spectroscopic methods. Crystal structures of B1, B2, B3 and B7 were determined by the X-ray crystallography techniques. Key Words: Hexachlorocyclotriphosphazene, spiro-, ansa-, bino- phosphazene compounds.
