Zeolite ZSM-11 as a reusable and efficient catalyst promoted improved protocol for synthesis of 2,4,5-triarylimidazole derivatives under solvent-free condition

Zeolite ZSM-11 catalyst was prepared by hydrothermal method and characterized by FTIR, XRD, SEM, HRTEM, EDS, and BET analysis techniques. The catalyst shows good catalytic activity toward synthesis of 2,4,5-triarylimidazole derivatives which is prepared by using benzil, aldehyde and ammonium acetate in solvent-free condition. The reaction, one pot synthesis is highly adaptable and eco-friendly and has several merits such as short reaction time, mild reaction conditions, and high yield. The ease of reusability and recovery of catalyst for five consecutive reactions makes this protocol highly suitable. Graphical abstract
