Abstract Two simple, efficient, and environmentally benign protocols for the synthesis of various N-arylacetamides via N-acetylation of arylamines and straightforward one-pot reductive acetylation of aromatic nitro compounds promoted by CuFe2O4 nanoparticles in water at reflux have been developed. The prepared CuFe2O4 MNPs are well known and fully characterized by various techniques. Furthermore, the CuFe2O4 NPs easily separated from the reaction environment using an external magnetic field and can be reused for several times without significant loss of its activity for both mentioned reactions.
