Efficientone-pot synthesis of imidazoles catalyzed by silica-supported La0.5Pb0.5MnO3 nano particles as anovel and reusable perovskite oxide

Abstract

Silica-supported La_0.5Pb_0.5MnO₃ nanoparticles was prepared and used as a new perovskite-type catalyst for rapid and efficient synthesis of substituted imidazoles by an one-pot three-component condensation of [9,10]-phenanthraquinone, aryl aldehydes and ammonium acetate in excellent yield under reflux, and also solvent-free conditions.
