A new, efficient and recoverable heterogeneous catalyst was successfully synthesized by functionalization of mesoporous silica FSM-16. The FSM-16/CPTMS-Rh-Ni(II) characterization with several techniques such as, XRD, TGA, FT-IR, SEM, EDX, BET and ICP. As a result, it was found that this synthesized compound acted as catalyst for many multi component reactions. These reactions included the synthesis of 2,4,5-triaryl-1H-imidazoles, 1,2,4,5-tetrasubstituted imidazoles and 3,4-dihydropyrimidine-2-(1H)-ones derivatives.
