We report that 2-hydroxyl benzophenones can be converted to phenyl salicylate esters by loss of an aryl group and O-acylation of the phenols. Iridium, cyclooctadiene, and bulky monodentate phosphine ligands catalyze the ketone C–C bond activation and fragmentation. We identified common side products in this process, which include C-acylation of the phenol reactant or trapping on cyclooctadiene. Several
