چکیده مقاله :
A Cobalt (II) Schiff-base complex immobilized mesoporous silica material (COSC@MCM-41) was prepared using the ultrasonication method. The formation of material with expected morphological and structural features was confirmed with various characterization techniques including UV-D, FTIR, SEM, EDAX and TEM analyses. Furthermore, the COSC@MCM-41 catalyzed Biginelli reaction has performed under an eco-friendly solvent approach at room temperature, achieving high product yield. The exhibition of excellent catalytic activity towards 3,4-dihydropyrimidone derivatives with high product yield in a short time at room temperature proved that the COSC@MCM-41 is a more effective heterogeneous catalyst toward the Biginelli reaction compared to other catalysts.
