Highly Practical “Ligand‐Free‐Like” Copper‐Catalyzed <i>N</i>‐Arylation of Azoles in Lower Nitrile Solvents

Abstract

Abstract In lower nitrile solvents, the N ‐arylation of azoles with aryl halides was achieved efficiently in the presence of copper powder without any additional ligands. Thus, the first nitrile type of monodentate ligand‐mediated, “ligand‐free‐like” copper‐catalyzed N ‐arylation procedure was established.
