In summary, a magnetically recyclable and highly efficient
Fe3O4–CuO nanocatalyst was designed and synthesized. The
catalyst used for a mild and efficient preparation of S-aryl
dithiocarbamates under Ullmann-type coupling reaction in
solvent-free conditions without using any base or ligand.
Various S-aryl dithiocarbamates were synthesized in good yield
under benign reaction conditions. This catalyst was found to be
stable and could easily separated by an external magnet and
reused for several cycles without signicant loss of its activity.
