  Simple base-free Miyaura-type borylation of triarylantimony diacetates with tetra(alkoxo)diborons under aerobic conditions

  摘要：

  The reaction of triarylantimony diacetates with tetra(alkoxo)diborons in the presence of PdCl2(PPh3)(2) (1 mol%) catalyst resulted in the Miyaura-type B-arylation to form arylboronates in moderate to good yields under base-free conditions. In the present reaction, two of the three aryl groups of antimony reagent were transferred to the coupling products when the reaction was carried out under aerobic conditions, although only one of the three aryl group of the antimony reagent was involved under an argon atmosphere. The broad scope of the reaction was demonstrated by using a variety of triarylantimony diacetates with sterically hindered aryl groups and highly reactive p-bromo-functionalized aryl derivatives.

• Merging Photoredox PCET with Ni-Catalyzed Cross-Coupling: Cascade Amidoarylation of Unactivated Olefins

  日期：2019.2

  integration of amidyl radicals with cross-coupling chemistry opens new avenues for reaction design. However, the lack of efficient methods for the generation of such radical species has prevented many such transformations from being brought to fruition. Herein, the amidoarylation of unactivated olefins by a cascade process from non-functionalized amides is reported by merging, for the first time, photoredox

  酰胺基自由基与交叉偶联化学的整合为反应设计开辟了新途径。然而，缺乏产生此类自由基物种的有效方法阻止了许多此类转化的实现。在本文中，首次报道了通过光氧化还原质子偶联电子转移（PCET）与镍催化的合并，通过级联法从非官能化酰胺进行的未活化烯烃的酰胺化。这项新技术可以在可见光催化剂和镍催化剂的存在下，从烯基酰胺，芳基和杂芳基卤化物中获得一系列包含特权吡咯烷酮核心的复杂分子。值得注意的是，该反应不限于酰胺-也可以使用氨基甲酸酯和脲。机理研究，

  We report here the ruthenium-catalyzed selective monoarylation of aromatic ketones bearing two ortho carbon–heteroatom (O or N) bonds. Under the newly developed catalyst system consisting of RuHCl(CO)(PiPr3)2, CsF, and styrene, the C–O arylation of 2′,6′-dimethoxyacetophenone with a phenylboronate gave the C–O monoarylation product selectively. The selective C–O monoarylation was applicable to a variety

  我们在这里报告了钌催化的带有两个邻位碳-杂原子（O或N）键的芳族酮的选择性单芳基化。在由RuHCl（CO）（P i Pr 3）2，CsF和苯乙烯组成的新开发的催化剂体系下，2'，6'-二甲氧基苯乙酮与苯基硼酸酯的C–O芳基化选择性地产生了C–O单芳基化产物。选择性C–O单芳基化反应适用于各种芳基硼酸酯和芳族酮，并具有较高的区域选择性和化学选择性。使用芳族酯的C–O单芳基化作为关键步骤，也可以实现正式的交替烯醇合成。

  Non‐activated alkyl electrophiles, including alkyl iodides, bromides, tosylates, mesylates, and even chlorides, underwent copper‐catalyzed cross‐coupling with aryl boron compounds and alkyl 9‐BBN reagents (see scheme; 9‐BBN=9‐borabicyclo[3.3.1]nonane). The reactions proceed with practically useful reactivities and thus complement palladium‐ and nickel‐catalyzed Suzuki–Miyaura coupling reactions of alkyl halides
