Sumario:In this paper, we report the synthesis of ZnFe(2)O(4)@SiO(2)@APTES@DHBS-Cu as a novel magnetic nanocatalyst, in a mild and green environment. The structure of the described magnetic compound was characterized by different physicochemical techniques including XRD, EDS, AAS, SEM, FT-IR, X-ray elemental mapping, TGA, and VSM analyses. The prepared magnetic nanoparticles exhibit excellent catalytic activity in synthesizing bis (pyrazolyl)methanes and oxidation of sulfide derivatives under green conditions. The heterogeneous nature of the catalyst was confirmed via the hot filtration experiment. Further, ZnFe(2)O(4)@SiO(2)@APTES@DHBS-Cu showed high efficiency and reusability that could be reused for at least five consecutive runs.
