  • <i>N</i>-Hydroxybenzimidazole as a structurally modifiable platform for <i>N</i>-oxyl radicals for direct C–H functionalization reactions
    作者:Tomomi Yoshii、Saori Tsuzuki、Shunya Sakurai、Ryu Sakamoto、Julong Jiang、Miho Hatanaka、Akira Matsumoto、Keiji Maruoka

    Methods for direct functionalization of C–H bonds mediated by N-oxyl radicals constitute a powerful tool in modern organic synthesis. While several N-oxyl radicals have been developed to date, the lack of structural diversity for these species has hampered further progress in this field. Here we designed a novel class of N-oxyl radicals based on N-hydroxybenzimidazole, and applied them to the direct C–H functionalization
    由N-氧基自由基介导的 C-H 键直接官能化方法构成了现代有机合成的有力工具。虽然迄今为止已经开发了几种N-氧基自由基,但这些物种缺乏结构多样性阻碍了该领域的进一步进展。在这里,我们设计了一类基于N-羟基苯并咪唑的新型N-氧基自由基,并将其应用于直接的 C-H 官能化反应。这些结构的灵活可修改特性使得能够轻松调整其催化性能。此外,利用这些有机自由基,我们开发了一种无金属方法来合成酰基氟,通过在温和条件下醛的直接 C-H 氟化。
  • Synthesis of acyl fluorides <i>via</i> photocatalytic fluorination of aldehydic C–H bonds

    demonstrate that acyl fluorides can be prepared directly from aldehydes via a C(sp2)–H fluorination reaction involving the inexpensive photocatalyst sodium decatungstate and electrophilic fluorinating agent N-fluorobenzenesulfonimide. This convenient fluorination strategy enables direct conversion of aliphatic and aromatic aldehydes into acylating agents.
    酰氟由于其独特的稳定性而成为通用的酰化剂。然而,它们的合成可能带来挑战,并且通常通过羧酸的脱氧氟化来完成。在这里,我们证明了酰氯可以直接由醛类通过C(sp 2)-H氟化反应制备,该反应涉及廉价的光催化剂脱卡酸钠和亲电氟化剂N-氟苯磺酰亚胺。这种方便的氟化策略可将脂族和芳族醛直接转化为酰化剂。
  • Versatile Palladium-Catalyzed Approach to Acyl Fluorides and Carbonylations by Combining Visible Light- and Ligand-Driven Operations
    作者:Yi Liu、Cuihan Zhou、Meijing Jiang、Bruce A. Arndtsen
    DOI:10.1021/jacs.2c01951
    日期:2022.6.1
    We describe the development of a general palladium-catalyzed carbonylative method to synthesize acyl fluorides from aryl, heteroaryl, alkyl, and functionalized organic halides. Mechanistic analysis suggests that the reaction proceeds via the synergistic combination of visible light photoexcitation of Pd(0) to induce oxidative addition with a ligand-favored reductive elimination. These together create
    我们描述了从芳基、杂芳基、烷基和官能化有机卤化物合成酰基氟化物的一般钯催化羰基化方法的发展。机理分析表明,反应通过Pd(0) 的可见光光激发的协同组合进行,以诱导氧化加成和配体有利的还原消除。这些共同创造了一个单向催化循环,不受一氧化碳配位的经典效应的抑制。将酰氟的催化形成与其随后的亲核反应相结合,开辟了一种以前所未有的广度进行羰基化反应的方法,包括高度官能化的含羰基产物的组装。
  • Cobalt-catalysed nucleophilic fluorination in organic carbonates

    2 and 3 were studied as catalysts in the fluorination of aromatic and aliphatic acyl chlorides in CH2Cl2, with 3 showing notably higher activities than 2. Subsequently, organic carbonates (dimethyl carbonate and propylene carbonate) were also employed as solvents, which led to shorter reaction times and to the broadening of the substrate scope to a variety of aliphatic halides. Comparative studies
    新型 P-N 配体 1-((二苯基磷烷基)甲基)-1 H-苯并-1,2,3-三唑 ( 1 ) 已制备,基于苯并三唑支架。1与[CoCp*(CH 3 CN) 3 ][BF 4 ] 2和[CoCp*(I) 2 ] 2 (Cp* = 五甲基环戊二烯基)反应得到螯合物[CoCp*(CH 3 CN)(P –N)][BF 4 ] 2 ( 2 ) 和 [CoCp*(I)(P–N)]I ( 3 ),分别。配合物2和3作为催化剂在 CH 2 Cl 2中芳族和脂族酰氯的氟化反应中进行了研究,其中3显示出明显高于2 的活性。随后,有机碳酸酯(碳酸二甲酯和碳酸亚丙酯)也被用作溶剂,这导致反应时间更短,底物范围扩大到各种脂肪族卤化物。3与类似络合物[CoCp*(I) 2 (PMePh 2)],其具有单齿膦配体,表明在前者的情况下获得了更高的产率。进行了 DFT 计算和实验研究,以阐明反应机制,这需要形成氟化钴物质,
  • Oxidation of Primary Aliphatic and Aromatic Aldehydes with Difluoro(aryl)-λ<sup>3</sup>-bromane
    作者:Masahito Ochiai、Akira Yoshimura、Md. Mahbubul Hoque、Takuji Okubo、Motomichi Saito、Kazunori Miyamoto
    DOI:10.1021/ol202248x
    日期:2011.10.21
    Oxidation of primary aliphatic aldehydes with p-trifluoromethylphenyl(difluoro)-lambda(3)-bromane in dichloromethane at 0 degrees C afforded acid fluorides selectively In good yields, while that of aromatic aldehydes In chloroform at room temperature produced aryl difluoromethyl ethers. A larger migratory aptitude of aryl groups compared to primary alkyl groups during a 1,2-shift from carbon to an electron-deficient oxygen atom in bromane(III) Criegee-type intermediates will result in these differences in the reaction courses.
