    摘要:
    据报道苄基硼酸酯直接氧化成酮。这种温和的Cu催化方法使用环境空气作为末端氧化剂,并且具有化学选择性。C-B键的氧化选择性发生,即使存在未保护的醇也是如此。初步研究表明,该反应通过烷基硼进行,以实现Cu的金属转移,过氧化物的形成和重排,从而生成羰基。

    Nickel-Catalyzed Borylation of Aryl- and Benzyltrimethylammonium Salts via C–N Bond Cleavage
    摘要:
    By developing a mild Ni-catalyzed system, a method for direct borylation of sp(2) and sp(3) C-N bonds has been established. The key to this hightly efficient C-N bond borylative cleavage depends on the appropriate choice of the nickel catalyst Ni(COD)(2), ICy center dot HCl as a ligand, and the use of 2-ethoxyethanol as the cosolvent. This transformation shows good functional group compatibility and can serve as powerful synthetic tool for gram-scale synthesis and late-stage C-N borylation of complex compounds.

  • Iron-Catalyzed, Markovnikov-Selective Hydroboration of Styrenes
    作者:Xu Chen、Zhaoyang Cheng、Zhan Lu
    DOI:10.1021/acs.orglett.7b00227
    日期:2017.3.3
    A highly Markovnikov-selective, iron-catalyzed hydroboration of styrenes is reported using available oxazolinylphenyl picolinamide as the ligand to afford the branched hydroboration products with up to >50/1 b/l. This reaction is operationally simple and could be carried out in gram scale.

    日期:——
    A palladium(II)-catalyzed hydroboration of aryl alkenes with stable and easy-to-handle (pinacolato)diboron (B2pin2) under mild conditions has been developed. Acetic acid acted as the solvent and the hydrogen source, which has been identified by deuterium experiments. Notably, isomerization–hydroboration of allyl benzene derivatives was observed. As a result, a series of benzyl boronic esters were obtained
    在温和的条件下,已开发出钯(II)催化的具有稳定且易于处理的(频哪醇)二硼烷(B 2 pin 2)的芳基烯烃加氢硼化反应。乙酸充当了溶剂和氢源,这已通过氘实验确定。值得注意的是,观察到烯丙基苯衍生物的异构化-硼氢化。结果,以中等至优异的产率获得了一系列苄基硼酸酯,并且具有唯一的区域选择性。
  • Highly Regio- and Enantioselective Copper-Catalyzed Hydroboration of Styrenes
    作者:Dongwan Noh、Heesung Chea、Junghwan Ju、Jaesook Yun

    日期:2009.8.3
    An existing challenge is the development of efficient regioselective catalytic systems that are compatible with stable hydroboration reagents and can be rendered enantioselective by the use of nonracemic ligands. Copper(I) complexes with chelating phosphines catalyzed the regio‐ and enantioselective hydroboration of styrenes with pinacolborane (PinBH) at room temperature to afford the corresponding
    现有的挑战是开发与稳定的硼氢化试剂兼容并可以通过使用非外消旋配体使其对映选择性的有效的区域选择性催化体系。在室温下,具有螯合膦的铜(I)配合物催化了频哪醇硼烷(PinBH)对苯乙烯的区域和对映选择性硼氢化反应,从而提供了相应的支链硼酸酯(请参见示例)。

    chemoselective conversion of the carbon-metal bond of gem-dimetallic reagents enables rapid and sequential formation of multiple carbon-carbon and carbon-heteroatom bonds, thus representing a powerful method for efficiently increasing structural complexity. Herein, we report a visible-light-induced, single nickel-catalyzed, chemoselective cross-coupling reaction between gem-borazirconocene alkanes and diverse
    宝石-双金属试剂的碳-金属键的直接和化学选择性转化能够快速、连续地形成多个碳-碳和碳-杂原子键,从而代表了一种有效增加结构复杂性的有效方法。在此,我们报告了一种可见光诱导的、单镍催化的、化学选择性交叉偶联的宝石-硼锆茂烷烃和多种芳基卤化物,以高产率提供了范围广泛的烷基 Bpin 衍生物,并具有出色的区域选择性。这种实用的方法具有非常简单的反应条件和广泛的底物范围。此外,我们系统地研究了 Bpin 导向的链行走过程,该过程是烷基二茂锆区域选择性的基础,从而揭示了用我们的方法实现的内烯烃远程官能化的机制。最后,DFT 计算表明该反应的高区域选择性源于 Bpin 基团的导向作用。

    日期:2021.7.16
    We report a Chan–Lam coupling reaction of benzylic and allylic boronic esters with primary and secondary anilines to form valuable alkyl amine products. Both secondary and tertiary boronic esters can be used as coupling partners, with mono-alkylation of the aniline occurring selectively. This is a rare example of a transition-metal-mediated transformation of a tertiary alkylboron reagent. Initial investigation
