The reaction of N-substitue-pyridly amine phosphazene compounds with benzotriazole and characterization of the products

In this study, at first stage, ten Schiff bases (S1-S10) were obtained from the condensation reactions of several methyl substitue 2-aminopyridines with salicylaldehyde, 5-chlorosalicylaldehyde and 5-bromosalicylaldehyde. N-substitue-2-pyridil-N-substitue-2-hydroxybenzyl amine ligants (L1-L10) were prepared with reduction of these Schiff bases with sodium borhydride. Spiro- phosphazenes were synthesized by nucleophilic substitution reactions of (L1-L10) ligants that were prepared with hexachlorocyclotriphosphazene (N3P3Cl6). Finally, full-substitue phosphazene compounds (B1-B10) were synthesized with benzotriazole, C6H5N3. The characterizations and spectral investigations of all compounds have been maden by elemental analyses, FT-IR, 1H-, 13C- ve 31P-NMR spectroscopic methods. In addition, crystal structures of compounds B4, B6, B9 and B10 were determined by the X-ray crystallography techniques.
