The condensation reaction of {N-[(2-hydroxyphenylmethyl)amino]-4,6-dimethylpyridine} (2), which is a reduction product of 1, with trimer N3P3Cl6 affords partially a substituted spiro-cyclic phosphazene derivative (3). The fully substituted phosphazenes (4 and 5) have also been obtained from the reactions of 3 with the excess of pyrrolidine and morpholine. The characterizations and spectral investigations of these compounds have been made by elemental analyses, FTIR, H-1-, C-13-, P-31 NMR, correlation spectroscopy (COSY), heteronuclear chemical shift correlation (HETCOR), heteronuclear multiple-bond correlation (HMBC) and mass spectroscopy (MS). The salient features of spectral data of these compounds have been discussed. (C) 2006 Elsevier B.V. All rights reserved.
