Bis(N-aryl) substituted oxalamides are effective ligands for promoting CuI-catalyzed aryl amination with less reactive (hetero)aryl chlorides at 120 °C with K3PO4 as the base in DMSO to afford a wide range of (hetero)aryl amines in good to excellent yields. Both the electronic nature and the steric property of the aromatic groups of the ligands are important for their efficiency.
