Synthesis of isoindolin-1-ones via palladium-catalyzed intermolecular coupling and heteroannulation between 2-iodobenzoyl chloride and imines

2-Iodobenzoyl chloride reacts with an array of imines in acetonitrile–methanol under carbon monoxide pressure in the presence of a catalytic amount of bis(triphenylphosphine)palladium(II) chloride/triphenylphosphine together with triethylamine to afford the corresponding isoindolin-1-ones in moderate yields.
