Abstract A ligand-free cooperative bimetallic iron/copper catalysis system was found to introduce various azoles and thiols onto 6-iodoimidazo[1,2-a] pyridine. After optimization, the inexpensive, nontoxic, air-stable, and commercially available CuO and FeCl2·4H2O enabled a regioselective N- and S-arylation of common nitrogen heterocycles and of a broad range of mercaptans including aliphatic, aromatic
