N‐(1‐Oxy‐2‐picolyl)oxalamic Acid as an Efficient Ligand for Copper‐Catalyzed Amination of Aryl Iodides at Room Temperature

N ‐(1‐Oxy‐pyridin‐2‐ylmethyl)oxalamic acid was identified as efficient ligand for CuI‐catalyzed amination of aryl halides at room temperature. In our catalytic system, N ‐arylation of cyclic secondary amines, primary amines, amino acids, and ammonia proceeded with moderate to excellent yields and high functional group tolerance.
