Nitroarenes as the Nitrogen Source in Intermolecular Palladium‐Catalyzed Aryl C–H Bond Aminocarbonylation Reactions

Abstract A three‐component palladium‐catalyzed aminocarbonylation of aryl and heteroaryl sp 2 C−H bonds using nitroarenes as the nitrogen source was achieved using Mo(CO) 6 as the reductant and origin of the CO. This intermolecular C−H bond functionalization does not requires any exogenous ligand to be added, and our mechanism experiments indicate that the palladacycle catalyst serves two roles in the aminocarbonylation reaction: reduce the nitroarene to a nitrosoarene and activate the sp 2 C−H bond.
