• 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。
