Reactivity of the P–N bond in the halide salts of bis[bis(diphenylphosphino)methylamine]platinum( II )

Conductivity measurements and 31P-{1H} NMR spectroscopy suggested that the chloride and iodide salts of bis[bis(diphenylphosphino)methylamine]platinum(II)[Pt(dppma)2]2+1 exist in solution equilibrium with the five-co-ordinate complexes [Pt(dppma)2X]+(X = Cl or I). The magnitude of the interaction of the iodide ion with 1 is greater than that of the chloride ion. The extent of formation of the halide-associated species is dependent upon the …
