CuO nanoparticles as effective reusable heterogeneous catalyst for S-arylation of tetramethylguanidine-heterocumulene adducts

The synthesis of a novel class of aryl bis(dimethylamino)methylenecarbamodithioates via CuO nanoparticles as an effective reusable heterogeneous catalyst for the S-arylation reaction of ۱,۱,۳,۳-tetramethylguanidine-heterocumulene adducts is described. The use of simple and readily available starting materials, mild copper-catalytic reaction conditions, no column chromatography, and good yields are remarkable specifications of this protocol.
