  C-H Activation by [Bis(dialkoxyphosphino)ethane]platinum(0) and [Bis(diaminophosphino)ethane]platinum(0) Complexes: Platinum-Platinum Dimer Formation Limits Yields

  摘要：

  Syntheses, of new bidentate phosphorus-containing ligands and platinacycles that insert into C-H bonds of unactivated hydrocarbons under mild conditions are reported. The reactivities of the platinum neopentyl hydride species can be substantially increased by introducing oxygen- or nitrogen-containing substituents onto the phosphorus atoms. Dimeric species that are formed from the Pt(0) species are identified by comparing their P-31 NMR spectra with simulated spectra. Further evidence for these dimers was obtained by cleaving them to mononuclear derivatives with alkyne and phosphine ligands. Formation of these dimers limits the efficiency of hydrocarbon activation. The extent of dimerization that occurs during alkane activation depends upon the steric crowdedness about the Pt(0) center. The X-ray structure of [-(CH2)4-C(CH2O)2]PCH2CH2P[(OCH2)2C-(CH2)4-]Pt(neo-Pe)Cl (9) has been determined: C21H39O4PtCl2.CH2Cl2, M(r) = 732.96, monoclinic, space group P2(1)/n (No. 14), a = 14.667(3) angstrom b = 11.384(6) angstrom, c = 17.110(4) angstrom, beta = 100.62(2)-degrees, V= 2808(3) angstrom3, z = 4, D(calc) = 1.734 g CM-3, mu(Mo Kalpha) = 54.74 cm-1, R = 0.048, R(w) = 0.055.
