  • Photoredox/Cobalt Dual Catalysis for Visible-Light-Mediated Alkene–Alkyne Coupling
    作者:Pramod Rai、Kakoli Maji、Biplab Maji
    DOI:10.1021/acs.orglett.9b01201
    日期:2019.5.17
    Dual photoredox transition-metal catalysis has recently emerged as a powerful tool for making synthetically challenging carbon–carbon bonds under milder reaction conditions. Herein, we report on the visible-light-mediated controlled generation of low-valent cobalt catalyst without the need for a metallic reductant. It enabled C–C bond formation via ene-yne coupling at room temperature. The generality
    最近,双重光化还原过渡属催化已成为一种在较温和的反应条件下制备具有挑战性的-键的有力工具。在本文中,我们报道了在不需要属还原剂的情况下可见光介导的低价催化剂的受控生成。它可以在室温下通过ene-yne偶联形成C–C键。这种双重催化的普遍性通过容纳多个官能团的可观分子多样性的创造得到证明。
  • Palladium-Catalyzed Decarboxylative Coupling of Alkynyl Carboxylic Acids and Aryl Halides
    作者:Jeongju Moon、Mihee Jang、Sunwoo Lee
    DOI:10.1021/jo802290r
    日期:2009.2.6
    2-Octynoic acid and phenylpropiolic acid were employed for the palladium-catalyzed decarboxylative coupling reaction and with a variety of aryl halides. The former needed 1,4-bis(diphenylphosphino)butane (dppb) as a ligand and the latter tri-tert-butylphosphine (PtBu3), and both required 2 equiv of tetra-n-butylammonium fluoride (TBAF) for full conversion. These reactions showed high reactivities and

    A series of N‐heterocyclic copper carbene complexes bearing sulfoxide and sulfone moieties have been prepared. In case of new copper compounds with sulfone ligand, the solid‐state structures were determined using X‐Ray crystallography. Obtained complexes were investigated as catalysts in such transformations as: 1,3‐dipolar cycloaddition of alkynes and azides (CuAAC), A3 coupling reaction and β‐hydroboration

  • Z-Stereoselective semi-reduction of alkynes: modification of the Boland protocol
    作者:Yasser M.A. Mohamed、Trond Vidar Hansen
    DOI:10.1016/j.tet.2013.03.038
    日期:2013.5
    Highly Z-selective semi-reduction of alkynes has been achieved by adding TMSCl to a mixture of Zn(Cu/Ag), water, and methanol. The conjugated Z-alkenes have been prepared in high yields at ambient temperature. The formation of isomeric E-alkenes and over-reduction to alkanes were suppressed in our modified Boland reduction protocol. The methodology was extended to the preparation of Z-substituted stilbenes
    通过将TMCSC1添加到Zn(Cu / Ag),甲醇的混合物中,可以实现炔烃的高度Z-选择性的半还原。在环境温度下已经以高收率制备了共轭Z-烃。在我们改进的Boland还原方案中,抑制了异构体E-烃的形成和烷烃的过度还原。该方法扩展到了Z-取代的对苯二甲酸的制备。
