A highly regioselective de-aryloxylative amination of O- or N-chelating group-functionalized 2-aryloxy quinolines has been accomplished by means of a copper catalyst. The chelating functional groups of the substrate play a crucial role in directing the C-

A copper-catalyzed regioselective direct amination of phenol derivatives with diarylamines via phenanthroline-based bidentate auxiliary-directed C-H cleavage has been developed. This reaction proceeds smoothly with only a copper salt and air as a terminal oxidant to produce the corresponding o-aminophenols in good yields. Moreover, the directing group can be easily attached, detached, and recycled. Additionally, preliminary computational studies of the reaction with DFT have also been performed.
