A metal-free method for the direct regioselective fluorination of anilides has been developed. In the presence of bis(tert-butylcarbonyloxy)iodobenzene (PhI(OPiv)(2)) and hydrogen fluoride-pyridine, the para-fluorination products of anilides were obtained in moderate to good yields. Because of its operational safety and the use of readily available reagents, this new procedure provides facile access to a variety of para-fluorinated anilides.
一种无需金属的方法被开发用于苯胺的直接区域选择性氟化。在双(叔丁基羰氧基)碘苯（PhI(OPiv)(2)）和氟化氢-吡啶的存在下，苯胺的对位氟化产物以中等至良好的产率得到。由于其操作安全性和使用易得的试剂，这种新方法为各种对位氟化苯胺提供了简便的途径。
