A general Pd-catalyzed double carbonylation of aryl iodides with secondary or primary amines to produce α-ketoamides at atmospheric CO pressure has been developed. This transformation proceeds successfully even at room temperature and in the absence of any ligand and additive. A wide range of aryl iodides and amines can be coupled to the desired α-ketoamides in high yields with excellent chemoselectivities
An effective green synthesis of α-ketoamides was developed for the first time in water via gold nanoparticles (AuNPs) catalyzedaerobicoxidative cross-dehydrogenative coupling of secondary amines with phenylglyoxals with a broad substrate scope.
has been accomplished using readily available cinnamic acids/arylacetic acids and 2° amines in an open atmosphere. The reaction between cinnamic acid and amine involves the formation of enamine followed by its aerobic oxidation, whereas the reaction of arylacetic acid with amine involves amide formation followed by benzylic methylene oxidation.

A simple and efficient gold-catalyzed coupling of secondary amine with phenylglyoxalderivatives has been developed, which provides a practical synthetic strategy for the synthesis of substituted α-ketoamides under mild reaction conditions.
