  摘要：

  The phosphite complexes cis-[PtMe2L(SMe2)] in which L = P((OPr)-Pr-i)(3), 1a, or L = P(OPh)(3), 1b, were synthesized by the reaction of cis, cis-[Me2Pt(mu-SMe2)(2)PtMe2] with 2 equiv. of L. If 4 equiv. of L was used the bis-phosphite complexes cis-[PtMe2L2] in which L = P((OPr)-Pr-i)(3), 2a, or L = P(OPh)(3), 2b, were obtained. The reaction of cis-[Pt(p-MeC6H4)(2)(SMe2)(2) ] with 2 equiv. of L gave the aryl bis-phosphite complexes cis[ Pt(p-MeC6H4)(2)L-2] in which L = P((OPr)-Pr-i)(3), 2a', or L = P(OPh)(3), 2b'. Use of 1 equiv. of L in the latter reaction gave the bis-phosphite complex along with the starting complex in a 1:1 ratio.The complexes failed to react with MeI. The reaction of cis, cis-[Me2Pt(mu-SMe2)(2)PtMe2] with 2 equiv. of the phosphine PPh3 gave cis-[PtMe2(PPh3)(2)] and cis-[PtMe2(PPh3)(SMe2)] along with unreacted starting material. Reaction of cis-[PtMe2L(SMe2)], 1a and 1b with the bidentate phosphine ligand bis(diphenylphosphino) methane, dppm = Ph2PCH2PPh2, gave [PtMe2(dppm)], 8, along with cis-[PtMe2L2], 2. The reaction of cis-[PtMe2L(SMe2)] with 1/ 2 equiv. of the bidentate N-donor ligand NN = 4,4'-bipyridine yielded the binuclear complexes [PtMe2L(mu-NN)PtMe2L] in which L = P((OPr)-Pr-i)(3), 3a, or L = P(OPh)(3), 3b. The complexes were fully characterized using multinuclear NMR (H-1, C-13, P-31, and Pt-195) spectroscopy. (C) 2008 Elsevier B.V. All rights reserved.

  paper describes the formation of newseries of platinum(II) complexes with phosphite and phosphine ligands. Treatment of cis,cis-[Me2Pt(μ-SMe2)2PtMe2] with 2 equimolar of L, L = P(OiPr)3orP(OPh)3, then adding 2 equimolar of L′, L′ = PPh3 or 4-MePy, gavecis-[Me2PtLL′] complexes,1a–4a, with some side products. Otherwise, reaction of cis,cis-[Me2Pt(μ-SMe2)2PtMe2] with 4 equimolar of Me2SO, then adding 2
