The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2,4,5-Triphenylimidazole( cas:484-47-9 ) is researched.COA of Formula: C21H16N2.Dipake, Sudarshan S.; Lande, Machhindra K.; Rajbhoj, Anjali S.; Gaikwad, Suresh T. published the article 《Zeolite ZSM-11 as a reusable and efficient catalyst promoted improved protocol for synthesis of 2,4,5-triarylimidazole derivatives under solvent-free condition》 about this compound( cas:484-47-9 ) in Research on Chemical Intermediates. Keywords: zeolite ZSM11 catalyzed synthesis arylimidazole benzyl aldehyde ammonium acetate. Let’s learn more about this compound (cas:484-47-9).
Zeolite ZSM-11 catalyst was prepared by hydrothermal method and characterized by FTIR, XRD, SEM, HRTEM, EDS, and BET anal. 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. Thus, e.g., benzil + 4-methylbenzaldehyde + ammonium acetate → 2-(4-methylphenyl)-4,5-diphenyl-1H-imidazole (85%).
