A general Pd-catalyzed double carbonylation of aryl iodides with secondary or primary amines provides α-ketoamides in high yields with excellent chemoselectivities at atmospheric CO pressure. This transformation proceeds successfully even at room temperature and in the absence of any ligand and additive.
