The reactions of a series of unsymmetrical, potentially bidentate ligands Ph2P(CH2)nX (n = 2, X = OMe, NMe2, SMe; n = 3, X = NMe2) with [PtX2(cod)] (X = Cl, I) are described. The tendency of the ligand to bond to the metal in a bidentate fashion is dependent on the nature of the weak donor, and on the size of the chelate ring formed. Halide abstraction by Ag+ promotes coordination of the ether function to yield [PtCl(Ph2PCH2CH2OMe)2]+ and [Pt(Ph2PCH2CH2OMe)2]2+. Reactions of the former with a number of weak donor ligands have been studied by 31P{1H} NMR spectroscopy. Complex mixtures are obtained with Ph2PCH2CH2SMe, and the involvement of ion-paired species is suggested in this case.
