| Abstract: | Abstract The synthesis of new derivatives of bis-(tetrachlorocyclotriphosphazenyl)-spermine was achieved upon reaction of some MONOSPIRO–N3P3Cl4HN–(CH2) n –NH] (n = 2,3,4) derivatives and of the gem–N3P3Az2Cl4 with spermine. All compounds were obtained in the monomeric state. 31P and 13C high-resolution NMR were used, together with IR spectroscopy and mass spectrometry, to assign molecular structures and to reveal conformational equilibria, if any. |
