An efficient, reusable copper-oxide/carbon-nanotube catalyst for N-arylation of imidazole

Copper oxide nanoparticles (CuONPs) were successfully decorated on acid treated multi-wall carbon nanotubes (f-MWCNTs) using copper acetate precursor by a very simple “mix and heat” method, and was used as a heterogeneous nanocatalyst for the N-arylation of imidazole for the first time. The transmission electron microscopic (TEM) images of the prepared nanocatalyst (CuO/MWCNT) showed a good adhesion of CuONPs on anchoring sites of the MWCNTs....
