• Expanding the Balz-Schiemann Reaction: Organotrifluoroborates Serve as Competent Sources of Fluoride Ion for Fluoro-Dediazoniation
  作者：Tharwat Mohy El Dine、Omar Sadek、Emmanuel Gras、David M. Perrin

  DOI：10.1002/chem.201803575

  日期：2018.10.9

  The Balz–Schiemann reaction endures as a method for the preparation of (hetero)aryl fluorides yet is eschewed due to the need for harsh conditions or high temperatures along with the need to isolate potentially explosive diazonium salts. In a departure from these conditions, we show that various organotrifluoroborates (RBF3−s) may serve as fluoride ion sources for solution‐phase fluoro‐dediazoniation

  Balz-Schiemann反应作为一种制备（杂）芳基氟化物的方法而持久，但由于需要苛刻的条件或高温以及需要分离潜在爆炸性的重氮盐而被避开。与这些条件不同，我们显示了各种有机三氟硼酸盐（RBF 3 - s）可以作为氟离子源，用于在温和条件下在有机溶剂中进行溶液相氟脱氮。该方法成功地扩展到一锅法，避免了芳基重氮盐的分离。受阻位的（杂）苯胺在前所未有的温和条件下以良好至优异的产率进行氟化。综上所述，这项工作扩大了RBF 3的功能范围-在经典的Balz-Schiemann反应的更新中充当氟离子源。

  The synthesis of aryl amines via the formation of a C−N bond is an essential tool for the preparation of functional materials, active pharmaceutical ingredients and bioactive products. Usually, this chemical connection is only possible by transition metal-catalyzed reactions, photochemistry or electrochemistry. Here, we report a metal-free arene C−H amination using hydroxylamine derivatives under benign

  通过形成 CN 键合成芳胺是制备功能材料、活性药物成分和生物活性产品的重要工具。通常，这种化学连接只能通过过渡金属催化的反应、光化学或电化学来实现。在这里，我们报告了在良性条件下使用羟胺衍生物进行的无金属芳烃 C-H 胺化。即使在存在各种官能团的情况下，胺化试剂 TsONHR 和芳烃底物之间的电荷转移相互作用也能实现芳烃的化学选择性胺化。氧气对于有效转化至关重要，其对电子转移步骤的加速作用已通过实验证明。此外，

  meta-substituted carboxylates are converted into para-substituted alkoxyarenes and vice versa. The combined processes provide a convenient synthetic entry to the important class of aromatic ethers from widely available carboxylic acids. A silver/copper bimetallic catalyst system promotes the decarboxylative Chan–Evans–Lam alkoxylation of ortho-substituted aromatic carboxylate salts with tetraalkyl orthosilicates

  摘要 银/铜双金属催化剂体系可促进原位取代的芳族羧酸盐与原硅酸四烷基酯或硼酸三芳基酯的脱羧化Chan-Evans-Lam烷氧基化反应。非邻位取代的羧酸盐通过邻-C-H-烷氧基化被烷氧基化，同时羧酸酯导向基团通过原脱羧作用被裂解。这样，间位取代的羧酸盐被转化为对位取代的烷氧基芳烃，反之亦然。组合的方法可以从广泛使用的羧酸中方便地合成进入重要类别的芳族醚。 银/铜双金属催化剂体系可促进原位取代的芳族羧酸盐与原硅酸四烷基酯或硼酸三芳基酯的脱羧化Chan-Evans-Lam烷氧基化反应。非邻位取代的羧酸盐通过邻-C-H-烷氧基化被烷氧基化，同时羧酸酯导向基团通过原脱羧作用被裂解。这样，间位取代的羧酸盐被转化为对位取代的烷氧基芳烃，反之亦然。组合的方法可以从广泛使用的羧酸中方便地合成进入重要类别的芳族醚。
