Ru‐catalyzed direct CH activation/meta‐bromination of arenes bearing pyridyl, pyrimidyl, and pyrazolyl directing groups has been developed. A series of bromo aryl pyridines and pyrimidines have been synthesized, and further coupling reactions have also been demonstrated for a number of representative functionalized arenes. Preliminary mechanistic studies have revealed that this reaction may proceed through
copper-catalyzed C-H halogenation of 2-aryl-pyridinescontaining a variety of electron-withdrawing and electron-donatingsubstituents was described. It is worth noting that cheap and easy-to-handlelithium halides were utilized as the halogen sources.
