  双核有机铂（II）配合物上的配体取代反应

  摘要：

  在双核dimethylplatinum（II）配合物式的N-供体配体的配位体取代反应顺，顺[我- 2的Pt（μ-NN）（μ-DPPM）PTME 2 ]，1，其中DPPM =双（通过不同的亲核磷供体L，L = P（O– i Pr）3或PPh 3和L 2  = dppm，形成二核配合物2，顺式，顺式-[Me 2 LPt] （μ-dppm）PtLMe 2 ]和顺式，顺-[Me 2 Pt（μ-dppm）分别研究了2 PtMe 2 ]。配合物1在可见光区域具有MLCT带，该MLCT带用于容易地追踪其配体取代反应的动力学。这些反应涉及含有顺铂-碳键的二铂（II）配合物1，是通过正常的缔合机理进行的。如预期的那样，在本研究的缔合反应中，反应速率取决于进入组的浓度和性质。PPh 3的亲核性强于P（O– i Pr）3基于其更强的σ供体能力和较低的溶剂化，并且是观察到的其速率与P（O– i Pr）3相比提高了

  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.
