A metal-free oxidative coupling of methyl ketones and primary or secondary amines to α-ketoamides has been developed. Four intermediates, α-iodoketone, α-aminoketone, iminium intermediate, and α-hydroxy amine have been identified through a series of control experiments. The atom-economic methodology can be scaled-up, tolerates a variety of functional groups, and is operationally simple.
