Abstract A copper-catalyzedaerobicoxidativecoupling of aryl methyl ketones with N,N-dimethylformamide was developed, which afforded α-ketoamides by a sequence of dioxygen activation, C–H bond functionalization, and amide formation with N,N-dimethylformamide as the nitrogen source. Molecular oxygen was found to play a crucial role in this transformation. A copper-catalyzedaerobicoxidativecoupling of aryl

form oxidative amidation product α-ketoamides and unusual degradative amidation product N-alkyl amides by simply changing the amine substitute. Atmospheric air containing molecular oxygen proved to be an ideal oxidant for an amidation reaction. Under similar conditions, the electron-deficient gem-dibromoalkenes play a dual role with different formamides forming novel oxidative amidation products and
