title: Phosphorus-nitrogen compounds: synthesis and spectral investigations on new spiro-cyclic phosphazene derivatives.
abstract: The condensation reaction of {N-[(2-hydroxyphenylmethyl)amino]-4,6-dimethylpyridine} (2), which is a reduction product of 1, with trimer N(3)P(3)Cl(6) 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, 1H-, 13C-, 31P 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.
