palladium-catalyzed chemoselective amination of chloro(hetero)aryl triflates in the C−Cl bond for the first time. A newly designed and synthesized alkyl-pyrazole-based phosphine ligand, L26 (BirdPhos), which is featured with the pyrazole ligand core and the cyclohexyl group at the C3 and C5 positions, was key to the success of this reaction. A variety of chloro(hetero)aryl triflates coupled with aromatic, aliphatic
