    卤离子在Pt(II)烷基和芳基络合物中PtC键的质子分解机理中的作用
    摘要:
    摘要描述了顺式-[PtPh 2(PEtPh 2)2]和反式-[PtXR(PEt 3)2](X = Cl and Br,R = Me ,在甲醇水溶液(MeOH / H 2 O,91v / v)中存在卤离子的情况下,通过质子对质子进行分析,得到Et,n-Pr,n-Bu,CH 2 Ph),生成顺式-[PtClPh(PEtPh 2)2]和反式-[PtX 2(PEt 3)2]。对于这两个系统,反应在底物中都是一阶的,并且服从一般的双变量率定律k obs = [H +] {k H + kx K [[X-]} /(1 + K [[X-]])。拟议中的机制涉及通过卤化物与正方形平面底物的相互作用快速实现铂(II)阴离子中间体的快速平衡前形成(K),同时结合底物(k H)和中间体的缓慢平行质子化(kx),导致金属碳σ键断裂。应该将中间体视为弱缔合产物,因为所有通过紫外,可见光和31 P {1 H} NMR光

  • Bond energies and thermal decomposition of [Pt(X)(CH3)(P(C2H5)3)2] complexes
    作者:A. Morvillo、G. Favero、A. Turco

    The thermal decomposition of the complexes trans-[Pt(X)(CH3)L2] (L  P(C2H5)3; X  Cl, Br, I, CN) in decalin at 170 and 200°C affords methane platinum metal and [Pt(X)2L2]. The kinetics of the decomposition of the complexes were determined by monitoring the appearance of methane by GLC. The observed first-order rate constant was found to be independent on the nature of the ligand X. The thermal decomposition

  • Ligand effects on the rates of protonolysis and isotopic exchange for platinum(II) alkyls
    作者:Matthew W. Holtcamp、Jay A. Labinger、John E. Bercaw
    DOI:10.1016/s0020-1693(97)05675-2
    日期:1997.11
    The protonolysis/deuterolysis of complexes L2PtRX (L = phosphorus ligand, R = alkyl group, X = anionic ligand) has been investigated as a mechanistic probe of the reverse reaction, activation of alkanes by Pt(II). Trans-(Et3P)(2)PtMeX (X- = triflate (OTf-), F-, NO3-) solvolyze in acidic CD3OD, forming [trans-(Et3P)(2)PtMe(CD3OD)](+) which reacts slowly with DOTf at room temperature liberating CH3D. In dichloromethane, trans-(Et3P)(2)PtMe(OTf) reacts with HOTf at low temperatures (-70 to -20 degrees C) to give (Et3P)(2)PtMe(H) (OTf)(2) in rapid equilibrium with the reagents, while at higher temperatures rapid methane loss is preceded by extensive deuterium incorporation (with DOTf) into the Pt(II) methyl group. Upon treatment with acid in CD3OD, trans-(Et3P)(2)PtMeX (X = Cl, Br) also undergo H/D exchange before elimination of methane, while trans-(Et3P)(2)PtMeI, (depe)Pt(CH3)(2) (depe=1,2-bis(diethylphosphine)ethane) and cis- [(MeO)(3)P] PtMeCl do not. The alpha hydrogens of trans-(Et3P)(2)PtRCl (R = Me, Et, Bz) exchange with deuterium in CD3OD/DOTf with rates following the order Bz < Me < Et, while no exchange is observed in the protonolysis of trans-(Et3P)(2)Pt(CH2CMe3)Cl which yields (CH3)(3)CCH2D. These trends are interpreted in terms of effects on relative stabilities of key intermediates, Pt(IV) alkyl hydrides and Pt(II) alkane sigma complexes. (C) 1997 Elsevier Science S.A.
