  Electro-reductive cyclization of aryl halides promoted by fluorene derivatives

  摘要：

  In the presence of fluorene derivatives, the electro-reduction of aryl chlorides, bromides, and iodides bearing an ethylene moiety proceeded smoothly to afford the corresponding cyclized products. Noteworthy is that aryl chlorides, which have more negative reduction potential than aryl bromides and iodides, exhibited high reactivity in the reaction, and the corresponding five-membered and six-membered cyclized products were obtained in good to high yields. Mechanistic study suggests that the electro-reduction of fluorene derivatives was essential for the reactions, indicating that they work as a mediator. (C) 2012 Elsevier Ltd. All rights reserved.

• Gold‐Catalyzed 1,2‐Diarylation of Alkenes
  作者：Chetan C. Chintawar、Amit K. Yadav、Nitin T. Patil

  DOI：10.1002/anie.202002141

  日期：2020.7.13

  Herein, we disclose the gold‐catalyzed 1,2‐diarylation of alkenes through the interplay of ligand‐enabled AuI/AuIII catalysis with the idiosyncratic π‐activation mode of gold complexes. Unlike the classical migratory‐insertion‐based approach to 1,2‐diarylation, the present approach not only circumvents the formation of direct Ar−Ar′ coupling and Heck‐type side products but more intriguingly demonstrates

  本文中，我们通过配体使能的Au I / Au III催化与金配合物的特质π活化模式的相互作用揭示了金的烯烃1,2-二芳基化反应。与经典的基于迁移插入的方法进行1,2-二芳基化不同，本方法不仅规避了直接Ar-Ar'偶联和Heck型副产物的形成，而且更有趣地证明了其反应性和选择性与先前已知的互补金属催化（Pd，Ni或Cu）。对机理进行详细研究的结果表明，由于芳基烯烃具有非清白的性质，芳基碘化物向Au I络合物的氧化加成是限速步骤。

  biology and drug development in recent years. Here, we report the development of a radical fluorosulfonylation of alkenes/intramolecular arylation cascade for the construction of chromanes with sulfonyl fluoride groups attached. The radical 1,2-fluorosulfonyl arylation reactions proceed well in both endo and exo cyclization fashions, allowing for further variation of the distance between the chromane core

  在生物活性分子中引入磺酰氟基团往往能带来生物活性的增强，近年来引起了化学生物学和药物开发领域更多的研究兴趣。在这里，我们报告了烯烃的自由基氟磺酰化/分子内芳基化级联的发展，用于构建带有磺酰氟基团的苯并二氢呋喃。自由基 1,2-氟磺酰基芳基化反应在内环化和​​外环化两种方式中都进行得很好，从而可以进一步改变色烷核与磺酰氟基团之间的距离。

  在此，我们报道了金催化的未活化烯烃与烯基碘化物和溴化物的芳基烯基化反应，采用配体启用的金氧化还原催化。目前的方法遵循 π 激活途径，而不是迁移插入途径，迁移插入途径在 Pd、Ni、Cu 等其他过渡金属催化中占主导地位。详细的机理研究，如 31 P NMR、氘标记和 HRMS研究已经已经进行以支持机械见解。
• Gold-catalyzed intramolecular hydroarylation of olefins. Scope evaluation and preliminary mechanistic studies
  作者：Mickael Jean、Pierre van de Weghe

  DOI：10.1016/j.tetlet.2011.04.122

  日期：2011.7

  We report a gold-catalyzed intramolecular hydroarylation of unactivated olefins using a combination of AuCl(3)/AgOTf as the catalytic system affording dihydrobenzopyrans, tetralins and tetrahydroquinolines in good yields. For our preliminary mechanistic studies, we have investigated the kinetic isotope effects with deuterated arene compounds and found that this catalytic hydroarylation is consistent with an electrophilic aromatic substitution process.
