Abstract

Abstract A new carbon monoxide-free, solvent-free, single step protocol for the synthesis of isoindole-1, 3-diones from o-haloarenes using palladium acetate and xantphos catalysis is reported. The wider applicability of this protocol for several types of o-iodoarenes and a few o-bromoarenes makes it attractive. Aryl iodides and aryl bromides provided moderate to excellent yields of up to 93%.
