  1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU)-Promoted Decomposition of Difluorocarbene and the Subsequent Trifluoromethylation

  摘要：

  Difluorocarbene derived from various carbene precursors could be effectively decomposed by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). This decomposition process was successfully applied in the subsequent trifluoromethylation of a variety of (hetero)aryl iodides without the addition of an external fluoride ion. Mechanistic investigation revealed the detailed difluorocarbene conversion process in which the decomposed difluorocarbene is finally transformed into a fluoride ion and carbon monoxide.

• Cathodic C–H Trifluoromethylation of Arenes and Heteroarenes Enabled by an in Situ-Generated Triflyltriethylammonium Complex
  作者：Wolfgang Jud、Snjezana Maljuric、C. Oliver Kappe、David Cantillo

  DOI：10.1021/acs.orglett.9b02948

  日期：2019.10.4

  While several trifluoromethylation reactions involving the electrochemical generation of CF3 radicals via anodic oxidation have been reported, the alternative cathodic, reductive radical generation has remained elusive. Herein, the first cathodic trifluoromethylation of arenes and heteroarenes is reported. The method is based on the electrochemical reduction of an unstable triflyltriethylammonium complex

  尽管已经报道了一些涉及通过阳极氧化电化学生成CF3自由基的三氟甲基化反应，但替代性的阴极，还原自由基的生成仍然难以捉摸。在此，报道了芳烃和杂芳烃的第一次阴极三氟甲基化。该方法基于电化学还原由廉价的三氟氯甲烷和三乙胺就地生成的不稳定的三氟三乙铵络合物，该络合物产生CF3自由基，这些自由基被芳烃捕获在阴极表面上。

  This communication describes the development of a mild method for the cross-coupling of arylboronic acids with CF(3)I via the merger of photoredox and Cu catalysis. This method has been applied to the trifluoromethylation of electronically diverse aromatic and heteroaromatic substrates and tolerates many common functional groups.
