Abstract: | The clean, environmentally benign and effective synthesis of novel azo-linked 4-arylpyrimidin-2(1H)-one derivatives and 4,6-bisarylpyrimidin-2(1H)-ones via three-component reaction of various aldehydes or synthetized azo-linked aldehydes, urea, and acetophenone promoted by NiFe2O4@SiO2nPr@glucose amine at room temperature (25 °C) was reported. NiFe2O4@SiO2nPr@glucose amine were synthesized and characterized by transmission electron microscope (TEM), fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometry (VSM), X-ray powder diffraction (XRD) and X-ray spectroscopy (EDX). These compounds were obtained in high yields and short reaction times. The catalyst could be easily recovered and reused for six cycles with almost consistent activity. The structures of the synthesized 4,6-bisarylpyrimidin-2(1H)-one compounds were confirmed by 1H NMR, 13C NMR and FTIR spectral data and elemental analyses. |
