An eco-friendly thiolation via diaryl disulfides and aryl iodides under ligand-free conditions is reported. With copper nanopowder as catalyst and PEG-400 as solvent, a variety of unsymmetrical diaryl sulfides are synthesized in good to excellent yields. The process is free from foul-smelling and unstable thiols and the copper nanopowder–PEG-400 catalytic system can be directly reused for four repetitive
