Copper-Catalyzed Amidation of Aryl Iodides in the Presence of Various Chelating Ligands

摘要

N,N'-Dibenzylethylenediamine is presented as a new, efficient, and versatile bidentate ligand suitable for the copper catalyzed formation of the C-N bond. This bidentate ligand has been demonstrated to facilitate the copper catalyzed cross-coupling reactions of aryl iodides with amides to afford the desired products in good to excellent yields.
