Resumen

Initially, a new organometallic catalyst with nano-silica gel substrate and Ni active center, namely nano-SiO2@nPr@DPyE-Ni was produced, and its properties were thoroughly debated. It was then applied with excellent performance to produce symmetric di-aryl sulfides (14 entries, 78–98%, 20–150 min, EtOH, and 70 °C), and 2-aryl-5-methyl-2,3-dihydro-1H-3-pyrazolones (12 entries, 91–98%, 2–4 min, solvent-free, and r.t). In both production routes, the nanocatalyst was recyclable and reusable for more than seven runs, and its heterogeneous nature was checked and confirmed through the recycling results, hot filtration test, and ICP-OES (coupled plasma optical emission spectroscopy) method.
