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.
