We described herein the importance of Ionic Liquids to synthesize in situ monodisperse copper nanoparticles with high surface area at room temperature. The in situ formed nanoparticles were characterized by Transmission Electron Microscopy (TEM), Energy-dispersive spectrometer (EDS) and X-ray powder diffraction (XRD) and shows excellent catalytic activity for cycloaddition reaction between azides with terminal alkynes to furnish 1,4-triazoles in excellent yields under mild conditions. The present catalytic system can take advantage of both ionic liquids and nanoparticles. The proposed catalytic system can minimize the time to synthesize copper nanoparticles with stabilizer and eliminates additional additives as well. (C) 2013 Elsevier Masson SAS. All rights reserved.
