A palladium-catalyzed aminocarbonylation of aryl and heteroaryl iodides under phosphine-free conditions enables the synthesis of primary amides in excellent yields using methoxylamine hydrochloride as an ammonia equivalent, that undergoes sequential carbonylation and demethoxylation under mild reaction conditions. The procedure does not require a phosphine ligand and takes place in short reaction times at low temperatures.
