  Vinyldisiloxanes: their synthesis, cross coupling and applications

  摘要：

  在开发五氟苯基二甲基硅烷作为新型有机硅交叉耦合试剂的研究中，发现活性硅醇盐和相应的二硅氧烷在碱性条件下迅速形成。二硅氧烷与硅醇盐之间的平衡发现，促使在无氟条件下将二硅氧烷用作交叉耦合反应的反应伙伴。我们之前的报告集中于芳基取代的乙烯基二硅氧烷与芳基卤化物的合成以及碱诱导的交叉耦合反应，取得了良好的产率和选择性。作为研究的延续，我们考察了影响烷基和芳基取代的乙烯基二硅氧烷交叉耦合反应成功的因素，并讨论了提出的机制。进一步研究扩展取代乙烯基二硅氧烷在交叉耦合中的广度和多样性，并应用于合成不对称的反式-stilbene和含有反式烯烃结构的环状化合物。

  4-Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C3H5)]2 system catalyses efficiently the Heck reaction of aryl halides with linear alkenes such as pent-1-ene, oct-1-ene or dec-1-ene. Selectivities up to 70% in favour of E-1-arylalk-1-ene isomers can be obtained. In the presence of cyclic alkenes the selectivities of the reactions strongly depends on the ring size. Addition to cyclohexene or cycloheptene led mainly

  During the studies towards the development of pentafluorophenyldimethylsilanes as a novel organosilicon cross coupling reagent it was revealed that the active silanolate and the corresponding disiloxane formed rapidly under basic conditions. The discovery that disiloxanes are in equilibrium with the silanolate led to the use of disiloxanes as cross coupling partners under fluoride free conditions. Our previous report focused on the synthesis and base induced cross coupling of aryl substituted vinyldisiloxanes with aryl halides; good yields and selectivities were achieved. As a continuation of our research, studies into the factors which influence the successful outcome of the cross coupling reaction with both alkyl and aryl substituted vinyldisiloxanes were examined and a proposed mechanism discussed. Further investigation into expanding the breadth and diversity of substituted vinyldisiloxanes in cross coupling was explored and applied to the synthesis of unsymmetrical trans-stilbenes and cyclic structures containing the trans-alkene architecture.
