Article Description

Abstract: Copper(I)–caffeine complex immobilized on silica-coated magnetite nanoparticles was successfully synthesized and fully characterized by analyzing FT-IR, X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray, inductively coupled plasma, thermal gravimetric analysis and vibrating sample magnetometer data. The catalytic activity of these magnetically retrievable nanoparticles was evaluated for green synthesis of 1,2,3-triazoles through the three-component reaction of various terminal alkynes with in situ generated organic azides from organic halides and epoxides in an aqueous medium that was observed to proceed well and products were obtained in good yields. In addition to showing outstanding catalytic activity, the magnetic catalyst is easy to synthesize and can be recycled at least five times with little loss in activity.
