ChemInform Abstract: β-Ketoimine as an Efficient Ligand for Copper-Catalyzed N-Arylation of Nitrogen-Containing Heterocycles with Aryl Halides

An efficient copper catalyst system, Cu2O/β-ketoimine L1, for the N-arylation of nitrogen-containing heterocycles with aryl iodides and bromides has been developed. The system works well with the electron-rich, -neutral, and -deficient aryl bromides to afford the products in good to excellent yields.
