      This work describes a mild and efficient approach for the synthesis of aryl amides via catalytic aminocarbonylation of aryl halides with alicyclic amines using a Pd(PtBu3)2/NH4Cl catalyst system. High chemoselectivity for mono-carbonylation reaction was achieved under mild reaction temperature and balloon pressure of CO. This work also discusses the catalytic intermediates in detail. The high selectivity should be attributed to the formation of an active acid chloride intermediate.
