Trifunctionalization of aryl iodides via intermolecular C–H acylation/intramolecular C–H alkylation achieved using palladium/norbornene cooperative catalysis

Herein, we describe a palladium/norbornene-catalyzed trifunctionalization of ortho -unsubstituted aryl iodides via a highly chemoselective cascade process involving intermolecular ortho acylation/intramolecular ortho alkylation/ ipso alkenylation.
