    oxidants. Herein we report a highly selective palladium-catalyzed cyclization reaction for the efficient synthesis of isatoic anhydrides from readily available o-iodoanilines, CO2, and CO. The reaction proceeds under mild conditions and is redox-neutral. Both CO2 and CO are indispensable C1 building blocks for this catalytic reaction.
