The synthesis of n-substitue-2-pyridil-n-substitue-2-hydroxybenzyl amine derivatives, the reactions with hexachlorocyclotriphosphazene and characterization of the products

In this study, at first stage, twelve Schiff bases (S1-S12) 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-L12) were prepared with reduction of these Schiff bases with sodium borohydride. Spiro- (1-12a) and ansa- (12b) type phosphazenes were synthesized at several solvent medium by nucleophilic substitution reactions of L1-L12 ligants that are prepared with hexachlorocyclotriphosphazene (N3P3Cl6). Full-substitue cyclo- phosphazene compounds (13-16) were synthesized from the reaction of spiro- and ansa- phosphazene compounds with several primer amines. Then, compounds 17, 18, 20 and 21 were obtained by the reactions of mono- and di-spiro- 2,2'-dihydroxy biphenyl substitue hexachlorocyclotriphosphazene with L7 and L10. Full-substitue compounds 19 and 22 were synthesized from the reaction of compounds 17 and 20 with pyrrolidine. The characterizations and spectral investigations of all compounds have been made by elemental analyses, MS, FT-IR, 1H-, 13C- ve 31P-NMR and HETCOR. Determination of the structure of some compounds were elucidated by further NMR methods like COSY and HMBC. In addition, crystal structures of compounds 1, 4 and 5 were determined by the X-ray crystallography techniques.
