  • Transfer of cyclopentadienyl groups between platinum atoms
    作者:Ronald J. Cross、Alistair J. McLennan
    DOI:10.1039/dt9830000359

    exclusively the same isomers of [PtCl(σ-C5H5)(CO)(PR3)]. The cyclopentadienyl groups do not transfer as fast as chloride ions between the same species, but do so considerably faster than any accompanying CO scrambling processes. Cyclopentadienyl groups from the σ-bonded complexes, and from [Pt(η5-C5H5)(PR3)2]Cl, can also be readily transferred to mercury when treated with HgCl2.
    用T1(C 5 H 5)或Hg(C 5 H 5)2中的环戊二烯基取代顺-[PtCl 2(CO)(PR 3)](PR 3 =叔膦)的氯离子的结果是:的异构体[氯铂酸(σ-C 5 H ^ 5)(CO)(PR 3)]以C 5 H ^ 5反式到PR 3。当过量的Tl(C 5 H 5) 用来。单取代或双取代化合物的σ键结合的环戊二烯基可以轻松地与顺式[[PtCl 2(CO)(PR 3)]]的化物在溶液中交换,再次仅产生[PtCl(σ-C)的相同异构体5 H 5)(CO)(PR 3)]。环戊二烯基在相同物种之间的迁移速度不如氯离子快,但迁移速度比任何伴随的CO加扰过程快得多。环戊二烯基从σ键合的复合物,并从[(η 5 -C 5 H ^ 5)(PR 3)2 ],也可以容易地转移到时的HgCl处理2。
  • Effect of organic groups on the carbonyl-insertion reaction of platinum(II)
    作者:Ronald J. Cross、James Gemmill
    DOI:10.1039/dt9810002317

    para-substituted aryl groups, R. Values of the equilibrium constants, enthalpy, and entropy of the reactions are presented. The electronic effects of the aryl groups on this R migration reaction are found to be at least as critical as any previously reported factors influencing this process. Electron-donating substituents in meta- or para-positions promote the insertions, whereas electron-withdrawing groups inhibit
    已经检查了进行CO插入的[PtCl(R)(CO)(PMePh 2)]的异构体与其卤代插入产物[Pt 2 Cl 2(COR)2(PMePh 2)2 ]之间的平衡,确定了12个邻位- ,元-和对位-取代的芳基基团,平衡常数,焓,反应的熵的R.数值表示。发现芳基基团对该R迁移反应的电子作用至少与先前报道的影响该过程的因素一样重要。供电子取代基中元-或对-位促进插入,而吸电子基团抑制它们。找到与Hammettσ值的相关性。由于空间原因,邻位取代基倾向于阻止该反应。吸电子基团的反应焓变负,这可能反映了增强的Pt-芳基键。
  • The effects of stereochemistry at platinum and the nature of the organic group on carbonyl insertion at [PtCl(R)(CO)(PMePh2)]

    undergoes carbonyl insertion, and produces the halide-bridged acyl complex [Pt2(µ-Cl)2(COPh)2(PMePh2)2], with which it equilibrates in solution. The other isomers are reluctant to undergo CO insertion, and attempts to promote this lead to elimination of carbon monoxide. Replacing the phenyl group by other R groups has a critical effect on the equilibrium position between the acyl and carbonyl complexes
    制备了[PtCl(Ph)(CO)(PMePh 2)]的三种几何异构体。仅具有Ph反式至PMePh 2的异构体容易进行羰基插入,并生成卤化物桥联的酰基络合物[Pt 2(µ-Cl)2(COPh)2(PMePh 2)2 ],使其在溶液中平衡。其他异构体不愿进行CO插入,并试图促进这一过程以消除一氧化碳。用其他R基团取代苯基对酰基和羰基络合物之间的平衡位置有关键影响,酰基的趋势按R = Et> Ph> Me> CH 2的顺序降低Ph(≃0)。这些观察结果与R迁移到CO作为(II)上的酰基形成的机理是相容的。
  • Organic group transfer reactions between platinum(II) and mercury(II)
    作者:Ronald J. Cross、Alistair J. McLennan

    one isomer only (Ph trans to CO) of [Pt(C5H5)Ph(CO)L]. These mixed diorganoplatinum complexes react with HgCl2 or cis-[PtCl2(CO)L] in chloroform to transfer specifically the organic group trans to L(C5H5) to Hg or Pt, respectively. The reaction between [PtCl(C5H5)(CO)L] (C5H5 trans to L) and Hg(CCMe)2 is complicated, producing initially both [Pt(C5H5)-(CCMe)(CO)L] and [PtCl(CCMe)(CO)L], but finally

  • Stereospecific transfer of ethynyl groups between platinum(II) and mercury(II)
    作者:Ronald J. Cross、James Gemmill
    DOI:10.1039/dt9840000199

    Treatment of these bis(ethynyl)platinum complexes with HgCl2 specifically removes the ethynyl trans to L, reforming (II) and the ethynylmercury(II) chloride. Reactions of the bis(ethynyl)mercurials can be advantageously carried out in the presence of [NEt4]Cl, which symmetrises the Hg(CCR)Cl by-product to Hg(CCR)2(thus making both ethynyls available for transfer to platinum) and [NEt4]2[Hg2Cl6](which
