| چکیده | ||
| Biosynthesis of Sm2O3 NPs using Sm(NO3)3.6H2O and double bloom purple Rose of Sharon in ethanol, produced an efficient catalyst for the synthesis of some nitrogen-containing heterocycles such as morpholine and piperidine derivatives. 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. | ||
