  摘要：

  The reactions of amides (RCONH2 and CF3SO2NH2) with L2Pd(CH3)2 and L2Pt(CH3)2 and with transient L2Pt0 to yield new complexes containing palladium- and platinum-amido nitrogen bonds are reported. Photolysis of Pt(C2O4)(PEt3)2 (1) in the presence of amide generates products of the type trans-PtH-(HNR)(PEt3)2 (R = SO2CF3 (1a), COCF3 (1b)). Reaction of amides with trans-PtH-(CH3)(PEt3)2 (2), cis-PdMe2(PEt3)2 (3), cis-PtMe2(PEt3)2 (4), PdMe2(dcpe) (5), PdMe2(dmpe) (6), and PtMe2(COD) (7) produces 1a,b, trans-PdMe(HNR)(PEt3)2 (R = SO2CF3 (3a), COCF3 (3b), COCF2H (3c), COPh (3d)), PtMe(HNR)(PEt3)2 (R = SO2CF3 (4a), COCF3 (4b)), PdMe(HNR)(dcpe) (R = SO2CF3 (5a), COCF3 (5b), COPh (5c)), PdMe(HNSO2CF3)(dmpe) (6a), and PtMe(HNR)(COD) (R = SO2CF3 (7a), COCF3 (7b)), respectively. The stereochemistry and topologies of the new compounds are established by multinuclear NMR spectroscopy. The relevance of these reactions to hydroamination catalysis is discussed.

  A class of unusually stable bis(silyl)palladium complexes is prepared by the reaction of a dinuclear Pd(I) hydride with either simple hydrosilanes or disilanes. The first structure of a palladium bis(silyl) compound and preliminary reaction chemistry with acetylenes are reported.

  The reaction of Pd-2(mu-dcpe)(2) (dcpe = 1,2-bis(dicyclohexylphosphino)ethane) with the bis(thiophosphinyl)disulfanes, R(2)P(S)SSP(S)PR(2) (R = Et, Ph), give the ionic complexes [(dcpe)Pd(SPR(2)S)](+)[SPR(2)S](-) in 60% (1; R = Et) and 72% (2; R = Ph) yields. An unusual dimer, (Et(2)PS(2))Pd}(2)(mu-Et(2)PS(2))(2), is also isolated in low yield for R = Et. The X-ray structure of a benzene solvate of 1 (C50H68P4S4Pd . 1.5C(6)H(6); monoclinic, a = 14.628(1) Angstrom, b = 16.662(3) Angstrom, c = 21.612(4) Angstrom, beta = 107.66(1), P2(1)/n, Z = 4, R = 0.047(F-0), R(w) = 0.056(F-0)) shows a nearly planar spirocyclic palladium atom in the cation and a free SPR(2)S(-) anion, Variable-temperature P-31 NMR spectra of 1 indicate rapid interchange of the coordinated and free SPR(2)S(-) counterion in solution at room temperature.
