An amido-directing regioselective and nucleophilic halogenation reaction of electron-rich amidophenols was realized in the presence of Fe(III) reagents. Halides could be sequentially introduced to specific positions to form mono-, di- and mixed di- halogenated amidophenols mostly in one-pot manner.
在 Fe(III) 试剂的存在下,实现了富电子氨基酚的酰胺定向区域选择性和亲核卤化反应。卤化物可以依次引入特定位置以形成单卤代、二卤代和混合二卤代氨基酚,主要以一锅法的方式进行。
