Sm2O3 nanoparticles have been confirmed by FT-IR, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Energy-dispersive X-ray spectroscopy (EDX). The products were obtained in moderate to good yields under mild reaction conditions and identified by CHN analysis, NMR, and FT-IR spectra. The catalyst could be easily separated from the reaction mixture by centrifugation, washed, dried, and re-entered to a fresh reaction mixture 4 times without considerable loss of activity.
