    摘要:
    据报道,由乙酸铜(II)催化的三乙氧基硅烷,二氧化硫和肼的三组分反应,导致N-氨基磺酰胺的收率很高。在二氧化硫的插入过程中,不仅三乙氧基(芳基)硅烷而且三乙氧基(烷基)硅烷均相容。另外,二乙氧基二芳基硅烷在该条件下也是合适的。

    Application of Directed Orthometalation toward the Synthesis of Aryl Siloxanes
    摘要:
    A selection of ortho-substituted aryl siloxanes have been prepared by directed orthometalation protocols. These siloxanes can be prepared in high yields and purity by use of a diverse selection of ortho-directing groups and electrophilic siloxane derivatives. The siloxanes are employed in palladium-catalyzed cross-coupling reactions with aryl bromides to generate unsymmetrical orthosubstituted biaryls in good to excellent yields.

  • Synthesis and Reactivity of Functionalized Arylcopper Compounds by Transmetalation of Organosilanes
    作者:Jessica R. Herron、Zachary T. Ball

    日期:2008.12.10
    and parcel of synthetic chemistry. Organosilanes potentially represent a cheap, robust, and environmentally benign precursor to reactive organometallics, but the nature of the very stable C−Si bond has generally prevented their use as precursors to more reactive organometallics. We present investigations into a copper fluoride complex which activates organosilanes in anhydrous media under mild conditions
    反应性有机金属是合成化学的重要组成部分。有机硅烷潜在地代表了反应性有机金属化合物的廉价、坚固且环境友好的前体,但非常稳定的 C-Si 键的性质通常阻止它们用作更具反应性的有机金属化合物的前体。我们对氟化铜络合物进行了研究,该络合物在温和条件下激活无水介质中的有机硅烷,实现金属转移以产生稳定且可分离的有机铜物种,其中包含敏感官能团,包括羰基、芳基溴、苄基氯和烷基酮。这一发现使我们能够更好地了解铜催化反应中假定中间体的基本反应性,并开发新的有机硅烷试剂催化键形成过程。

  • Improved Synthesis of Aryltriethoxysilanes via Palladium(0)-Catalyzed Silylation of Aryl Iodides and Bromides with Triethoxysilane
    作者:Amy S. Manoso、Philip DeShong
    DOI:10.1021/jo010621q
    日期:2001.11.1
    silylation of aryl halides with triethoxysilane has been expanded to include aryl bromides. A more general Pd(0) catalyst/ligand system has been developed that activates bromides and iodides: palladium(0) dibenzylideneacetone (Pd(dba)(2)) is activated with 2-(di-tert-butylphosphino)biphenyl (Buchwald's ligand) (1:2 mol ratio of Pd/phosphine). Electron-rich para- and meta-substituted aryl halides (including

  • Preparation and Palladium-Catalyzed Cross-Coupling of Aryl Triethylammonium Bis(catechol) Silicates with Aryl Triflates
    作者:W. Michael Seganish、Philip DeShong
    DOI:10.1021/jo035309q
    日期:2004.2.1
    Pentavalent aryl and heteroaryl bis(catechol) silicates undergo palladium-catalyzed cross-coupling with aryl and heteroaryl triflates in the presence of a fluoride source in excellent yields. These solid, air-stable bis(catechol) silicates are prepared from a high-yielding displacement reaction between catechol and an aryl siloxane in the presence of an amine base. The cross-coupling reaction is tolerant

  • Nickel-Catalyzed Monofluoroalkylation of Arylsilanes via Hiyama Cross-Coupling
    作者:Yun Wu、Hao-Ran Zhang、Yi-Xuan Cao、Quan Lan、Xi-Sheng Wang
    DOI:10.1021/acs.orglett.6b02803
    日期:2016.11.4
    first example of nickel-catalyzed monofluoroalkylation of arylsilanes has been developed with readily available fluoroalkyl halides. This novel transformation has demonstrated high reactivity, broad substrate scope, excellent functional group tolerance, and mild reaction conditions. The selective activation of a relatively inert C–Si bond for slow release of aryl carbanion is the key reason for reducing
    用容易获得的氟代烷基卤化物开发了镍催化的芳基硅烷单氟烷基化的第一个例子。这种新颖的转化已显示出高反应活性,广泛的底物范围,出色的官能团耐受性和温和的反应条件。选择性活化相对惰性的C-Si键以缓慢释放芳基碳负离子是减少芳基金属种类数量的关键原因,这使该方法对于复杂生物活性分子的含氟修饰更具前景。机理研究表明,该催化循环涉及游离的氟代烷基。
