A convenient, efficient and ligand-free method for the C-N coupling reaction of anilines and aryl iodides was performed using CuCr 2 O 4 nanoparticles. Copper chromite nanocatalyst improved the rate and facility of the synthesis of triarylamines. The heterogeneous catalyst was fully characterized by scanning electron microscopy, IR and X-ray diffraction techniques. Recyclability, excellent yields of products and short reaction times are the important advantages of this ligand-free procedure by using the CuCr 2 O 4 nanoparticles.
