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

A convenient and efficient protocol has been developed for the cross-coupling of amides and aryl iodides using a ligand-freecopper(I) oxide catalyst in water. A variety of amide derivatives afforded the corresponding N-arylated products in moderate to good yields (up to 88%).
