An efficient ligand-free protocol for the amincocarbonylation of aryl iodides with aromatic and aliphatic amines afforded the desired amides in excellent yields using a low loading of palladium(II) acetate as catalyst in water under mild operating conditions. The system tolerated a wide variety of hindered and functionalized substrates.

Molybdenum hexacarbonyl is a convenient and solid carbon monoxide source in a microwave-accelerated palladium-catalyzed aminocarbonylation of aryl bromides and iodides. 16 different aromatic amides were synthesized under air in good yields after only 15 min of controlled microwave irradiation.
