Bu4NI-Catalyzed Oxygen-Centered Radical Addition between Acyl Peroxides and Isocyanides

A novel oxygen-centered radical addition between acyl peroxides and isocyanides has been developed. A diverse collection of valuable arylcarboxyamides were easily synthesized by this protocol. From the preliminary mechanistic study, the elimination of carbon dioxide affords the product via an intramolecular rearrangement.
