Palladium‐Catalyzed Oxidative Carbonylation of Diarylamines for the Synthesis of Acridone Derivatives

A Pd‐catalyzed oxidative dual C−H carbonylation has been developed starting from commercially available diarylamines, in which the Cr(CO)6served as a safe carbonyl source. This method provides a facile and atom‐economic approach toward diversified acridone derivatives in moderate to good yields, which features with good functional group compatibility, operational safety and easy scale‐up.
