    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.

    Comparison of Arylboron-Based Nucleophiles in Ni-Catalyzed Suzuki–Miyaura Cross-Coupling with Aryl Mesylates and Sulfamates
    摘要:
    The efficiency of arylboron-based nucleophiles, boronic acid, potassium trifluoroborate, neopentylglycolboronate, and pinacol boronate in nickel-catalyzed Suzuki-Miyaura cross-coupling reactions with the two C-O electrophiles, mesylates, and sulfamates was compared. Arylboronic acid is the most reactive and most atom-economic of the four boron species studied. Arylpotassium trifluoroborate cross-couples efficiently only in the presence of water. la the absence of water, aryl neopentylglycolboronate is more efficient, less expensive, and more atom-economic than aryl pinacolboronate.

  • RuH2(CO)(PPh3)3-catalyzed arylation of aromatic esters using arylboronates via C–H bond cleavages

    The RuH2(CO)(PPh3)3-catalyzed C–H functionalization of aromatic esters with 5,5-dimethyl-2-aryl-[1,3,2]dioxaborinanes (arylboronates) gave the ortho arylation products. This coupling reaction can be performed with various combinations of isopropyl benzoate derivatives and arylboronates. Introduction of CF3 group in the aromatic ring increased the reactivity of the esters. Pinacolone effectively served
    RuH 2(CO)(PPh 3)3催化的芳香族酯与5,5-二甲基-2-芳基-[1,3,2]二氧杂硼烷酮(芳基硼酸酯)的C–H官能化反应得到邻芳基化产物。该偶联反应可以用异丙基苯甲酸酯衍生物和芳基硼​​酸酯的各种组合进行。在芳环中引入CF 3基团增加了酯的反应性。Pinacolone有效地充当了由C–H键断裂产生的氢化物的接受体,并且使用的pinacolone的量也影响了芳基化产物的收率。

    A zinc(II)/NHC system catalyzes the borylation of aryl halides with diboron (4) reagents in the presence of KOMe at rt. This transformation can be applied to a broad range of substrates with high functional group compatibility. Radical scavenger experiments do not support a radical-mediated process.

    日期:2007.3.1
    Dialkyl oxalates undergo selective diarylation on one of their carbonyl carbons upon treatment with arylboron reagents in the presence of a rhodium catalyst to give the corresponding α-hydroxydiarylacetates. Under similar conditions, the arylation of benzoylformate and benzil also proceeds efficiently.

The reaction is applied to late‐stage modifications of various densely functionalized medicinally relevant molecules. Preliminary mechanistic studies suggest that a rare enantioselective η2‐coordinating activation of ketone carbonyls is involved. This crosscoupling‐like mechanism is expected to enable other challenging
    据报道,一般高效,高度对映和化学选择性的N-杂环卡宾(NHC)/ Ni催化将易于获得的稳定的芳基硼酸酯加到酮中。该协议可提供出乎意料的快速访问权限(通常为10分钟),这些手性叔醇具有特别宽的底物范围和出色的官能团耐受性(76个示例,最高98%ee)。此过程与其他已知的Ni介导的Suzuki-Miyaura偶联正交,因为它可以耐受芳基氯,氟化物,醚,酯,酰胺,腈和烷基氯。该反应适用于各种紧密功能化的医学相关分子的后期修饰。初步机理研究表明,一种罕见的对映选择性η 2涉及酮羰基的配位活化。这种类似交叉耦合的机制有望实现酮类的其他挑战性转化。

    A catalytic method for the site‐selective and enantioselective synthesis of functionalized arenes by the intermolecular hydroarylation of terminal and internal 1,3‐dienes with aryl pinacolato boronates is reported.
