Preparation of alumina supported copper nanoparticles and their application in the synthesis of 1,2,3-triazoles
چکیده انگلیسی

We report here the synthesis of alumina supported copper nanoparticles from copper(II) acetylacetonate and aluminum isopropoxide precursors using aerogel protocol. The nanoparticles were characterized by XRD, TEM, 27Al MAS NMR, XPS and ICP-AES. Cu-Al2O3 nanoparticles are used for the preparation of 1,2,3-triazoles by the reaction of terminal alkynes, sodium azide and alkyl/allyl halides. The nanoparticles are recovered and reused for several cycles with consistent activity.
