Reactions of Platinum Nitrile Complexes with Cyclotriphosphazenes Containing Pyridylalkylamino Groups

摘要

Reactions of platinum(II)and platinum(IV)nitrile complexes with polydentate ligands,such as pentaphenoxy(2-pyridylmethylamino)cyclotriphosphazene,pentaphenoxy(3-pyridylmethylamino)cyclotri-phosphazene,and pentaphenoxy(2-pyridylethylamino)cyclotriphosphazene,were studied.Platinum(IV)is reduced to platinum(II)upon complex formation;the pyridine and alkylamine nitrogen atoms coordinate to platinum(II)to form chelate rings.The compounds obtained were characterized by ~1H and ~(31)P NMR and IR spectroscopy,FAB mass spectrometry,and other methods.
