The Cl substitution reaction of N3P3Cl6
(1) with N-(2-pyridyl)-methyl-N'-methylpropane-1,3-diamine
(2) afforded the partly substituted 2-pyridyl(N/N)spirocyclotriphosphazene
(3) (with a yield of 57%) in dry THF.
When the Cl replacement reactions of 2 carried
out with
excess pyrrolidine, morpholine and 1,4-dioxa-8-azaspiro[4,5]decane (DASD), the corresponding 2-pyridyl(N/N)spirotetrapyrrolidino (3a),
tetramorpholino (3b) and tetra(1,4-dioxa-8-azaspiro[4,5]decano) (3c) cyclotriphosphazenes were prepared in moderate
yields. The structures of four cyclotriphosphazene
derivatives were elucidated by the elemental
analyses, Fourier transform infrared (FTIR),
heteronuclear mass spectrometry (ESI-MS), heteronuclear multiple-bond
correlation (HMBC), single quantum coherence (HSQC), 1H, 13C,
and 31P NMR techniques.
