    Pd(OAc)2/o-Chloranil/M(OTf)n: A Catalyst for the Direct C–H Arylation of Polycyclic Aromatic Hydrocarbons with Boryl-, Silyl-, and Unfunctionalized Arenes
    摘要:
    Pd(OAc)(2)/o-chloranii/M(OTf)(n) can effectively promote the C-H arylation of fluoranthene with arylboron compounds or arylsilanes. The reaction takes place with high regloselectivity at the C3 position of fluoranthene. Moreover, the new catalytic system allows the use of unfunctionalized arenes as coupling partners in the arylation of polycyclic aromatic hydrocarbons.

  • Internal B–O Bond-Facilitated Photoisomerization of Boranes: Ring Expansion Versus Oxyborane Elimination/Intramolecular Diels–Alder Addition
    作者:Guo-Fei Hu、Hai-Jun Li、Chao Zeng、Xiang Wang、Nan Wang、Tai Peng、Suning Wang
    DOI:10.1021/acs.orglett.9b01892
    日期:2019.7.5
    B–O bond have been found to undergo facile multistructural transformations upon irradiation at 365 or 410 nm, generating rare 8-membered B,O-heterocycles (1c–4c). In addition, 2 and 3 also undergo an intramolecular Diels–Alder addition and oxyborane elimination concomitantly, via intermediates 2b/3b, producing 2d/3d. The pathways to isomer c and product d were found to be a thermal process and a photo

    We have discovered that the combination of Pd(OAc)(2)/o-chloranil can catalyze the direct C-H bond arylation of polycyclic aromatic hydrocarbons (PAHs) with arylboroxins that occurs selectively at the K-region. The sequential integration of Pd-catalyzed direct arylation of PAHs and FeCl(3)-mediated cyclodehydrogenation is effective in rapidly extending a parent PAH π-system with high directionality
    我们发现 Pd(OAc)(2)/邻氯苯醌的组合可以催化多环芳烃 (PAH) 与芳基环硼氧烷的直接 CH 键芳基化,该反应选择性地发生在 K 区。Pd 催化的 PAHs 直接芳基化和 FeCl(3) 介导的环化脱氢的顺序整合可有效地快速扩展具有高方向性的母体 PAH π 系统。
  • Rhodium-Catalyzed Synthesis of Amides from Functionalized Blocked Isocyanates
    作者:Joshua S. Derasp、André M. Beauchemin
    DOI:10.1021/acscatal.9b02641
    日期:2019.9.6
    Isocyanates are useful building blocks for the synthesis of amides, although their widespread use has been limited by their high reactivity, which often results in poor functional group tolerance and a propensity to oligomerize. Herein, a rhodium-catalyzed synthesis of amides is described coupling boroxines with blocked (masked) isocyanates. The success of the reaction hinges on the ability to form
    异氰酸酯是酰胺合成的有用组成部分,尽管它们的广泛使用受到其高反应性的限制,这通常导致较差的官能团耐受性和低聚倾向。在本文中,描述了铑催化的酰胺的合成,其将环硼氧烷与封闭的(被掩蔽的)异氰酸酯偶联。反应的成功取决于原位形成异氰酸酯和有机铑中间体的能力。依赖于掩蔽的异氰酸酯前体和有机铑中间体的高反应性,可实现宽泛的官能团耐受性,包括质子亲核基团(如胺,苯胺和醇)。
  • Parameterization of phosphine ligands demonstrates enhancement of nickel catalysis via remote steric effects
    作者:Kevin Wu、Abigail G. Doyle
    DOI:10.1038/nchem.2741
    日期:2017.8
    Ligand development underlies many advances in Pd-catalysed cross coupling but has seen limited application in the growing field of Ni catalysis. Now, a phosphine framework is shown to enable Ni-catalysed Suzuki coupling of acetals. Parameterization studies provide structural insight into ligand success and a quantitative model to facilitate further ligand design.

    The reaction of tris(trimethylsilyl)methylboron dihalides (Me3Si)3CBX2 (X = Cl, F) with the lithium phosphides LiPHtBu and LiPHmes leads to the phosphinoboranes (Me3Si)3CBX-(PHR), (Me3Si)3CB(PHR)2 or the 1,3,2,4-diphosphadiboretanes [(Me3Si)3CB(PR)]2, depending on the ratio of the reagents, the reaction temperature and concentration. High dilution and low temperatures are required for the synthesis
