Abstract
In this study, a new organometallic catalyst including polymeric imidazolium ionic liquid-functionalized Mn(III) Schiff base complex (PIL-SB-Mn(III)) was prepared and characterized using various analyses like FTIR, H-NMR, FE-SEM, EDX, TGA, and ICP-OES. Then, the applications of catalyst were tested in the synthesis of 3,4-dihydropyrimidine-2(1H)-one/thiones under solvent-free conditions. This polymeric ionic liquid catalyst can carry out the Biginelli reaction in less than an hour in good to excellent yields. The recovered catalyst has been characterized by FTIR and EDX analyses; heterogeneous nature of this catalyst has been confirmed successfully.
