Nano magnetite functionalized 2,2′-biimidazole complex of metal ions Cu(i), Cu(ii), Ni(ii) and Co(ii) were successfully synthesized and characterized by different techniques such as elemental analysis, FT-IR spectroscopy, X-ray diffraction (XRD), thermo gravimetric analysis (TGA), transmission electron microscopy (TEM), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM with EDS), atomic absorption spectroscopy (AAS), inductively coupled plasma-optical emission spectrometry (ICP-OES) and vibrating sample magnetometer (VSM) instrument. The synthesized magnetic nanoparticles were used as heterogeneous catalysts for the synthesis of propargylamines via the three-component coupling reaction of aldehydes, alkynes and amines and one-pot synthesis of 1,4-disubstituted 1,2,3-triazoles by the click reaction of primary halides or tosylates, sodium azide and terminal acetylenes in aqueous media. The prepared nanocatalyst can be facilely recovered and reused many times without a significant decrease in activity and selectivity. The high catalytic activity, thermal stability and reusability, simple recovery and eco-friendly nature of the catalyst make the present method particularly attractive in green chemistry.
