Platinum(II) complexes containing 1-(diphenylphosphino)-2-methoxyethane. 31P NMR and catalytic studies in the presence of tin(II) chloride and the crystal and molecular structure of [Pt(Ph2PCH2CH2OMe)(Ph2PCH 2CH2OMe)Cl]ClO4

The complexes [PtCl2-n(Ph2PCH2CH2OMe) 2]n+ (n = 0, 1, 2) react with SnCl2·2H2O in acetone or chloroform solution to produce [PtCl(Ph2PCH2CH2OMe)3]+ and series of tin-containing platinum(II) anions. The tin(II) chloride serves three functions: inserts into Pt-Cl bonds to form the trichlorostannate ligand, acts as a source of chloride ions, and maintains electroneutrality by forming hydroxy-tin cations. Such solutions catalyze the hydrogenation of styrene, the catalytic activity showing little dependence on the solvent employed. The crystal structure of chloro[1-(diphenylphosphino)-2-methoxyethane-O,P][1-(diphenylphosphino)-2- methoxyethane-P]platinum(II) perchlorate (n = 1) has been determined by X-ray crystallography. It crystallizes in the monoclinic space group P21/c with 4 formula units/cell of dimensions a = 10.266 (3), b = 18.767 (7), and c = 16.581 (7) A? and β = 101.23 (3)°. Least-squares refinement of 370 parameters using 3032 reflections yielded R = 0.039. The structure consists of distorted square-planar [Pt(Ph2PCH2CH2OMe)(Ph2PCH 2CH2OMe)Cl]+ cations and perchlorate anions. One of the two identical phosphorus-oxygen ligands functions as a bidentate ligand and the second as a unidentate ligand coordinated through the phosphorus atom. The coordinated phosphorus atoms are cis to one another, and a chloro ligand trans to the phosphorus atom of the bidentate ligand completes the square-planar coordination about the Pt(II) center. The Pt-O bond distance of 2.192 (7) A? is the longest reported platinum-ethereal oxygen bond distance.

Platinum (II) complexes of unsymmetrical, potentially bidentate ligands

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.
