Cu-Catalyzed Direct Amidation of Aromatic C–H Bonds: An Access to Arylamines
摘要:
A Cu-catalyzed aromatic C-H amidation with phthalimide under oxygen as a terminal oxidant without using additional additives has been achieved. This reaction has the broad substrate scope and shows moderate to good yields in most cases. This method is complementary to the previously reported metal-catalyzed C-H amination systems.

Rhodium(III)-catalyzed C-H-activation amidation of arenes bearing chelating groups has been achieved using N-arenesulfonated imides as efficient amidating reagents without using any base additive. Pyridine, oxime, and pyrimidine proved to be viable directing groups.
