Double carbonylation of aryl iodides with amines under an atmospheric pressure of carbon monoxide using sulfur-modified Au-supported palladium

A double carbonylation of aryl iodides with amines proceeded smoothly under an atmospheric pressure of carbon monoxide by using palladium nanoparticles (Pd NPs) leached from a sulfur-modified Au-supported palladium material (SAPd), producing alpha-ketoamides in good to excellent yields.
