practical synthesis of aryl and heteroaryl N‐acylureas has been developed via palladium‐catalysed carbonylation of aryl or heteroaryl halides in the presence of urea nucleophiles. A range of reactions illustrating the wide scope of this reaction was carried out under microwave irradiation, using either carbonmonoxide gas in a vessel equipped with a gas inlet adapter, or molybdenumhexacarbonyl as the
