  method enables non‐directed functionalization of C−H bonds on a range of substrates, providing access to aryl trifluoromethyl ethers. This light‐driven process is distinctly different from conventional procedures and occurs through an OCF3 radical mechanism mediated by a photoredox catalyst, which triggers an N−O bond fragmentation. The pyridinium‐based trifluoromethoxylation reagent is bench‐stable and

  一种简单的三氟甲氧基化方法可以在一系列底物上实现CH键的非定向功能化，从而可以使用芳基三氟甲基醚。这种光驱过程与传统方法有明显不同，它是通过光氧化还原催化剂介导的OCF 3自由基机理发生的，该机理引发了N-O键断裂。基于吡啶鎓的三氟甲氧基化试剂具有台式稳定性，可通过操作简单的方式获得铅化合物的合成多样性。

  of arenes and heteroarenes under continuous-flow conditions is described. Application of continuous-flow microreactor technology allowed to reduce the residence time up to 16 times in comparison to the batch procedure, while achieving similar or higher yields. In addition, the use of inorganic bases was demonstrated to increase the reaction yield under batch conditions.
