monoamidation of aromatic ketones, chalcone, carbazole, and benzophenones was achieved by employing high‐valent cobalt and rhodium catalysis to access numerous biologically important molecular building blocks. This amidation proceeded smoothly with a variety of ketones and several amidating partners. The application of the products in the synthesis of various heterocycles, including acridones, indoles, quinoline
