Silica-supported La0.5Pb0.5MnO3 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.

A novel acidic ionic liquid based on imidazoliumcation is designed, synthesized, and successfully used as a catalyst for the one-pot synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazole derivatives. The remarkable feature of this new catalyst is its ethyleneoxy bridge which participates in dissolving organic compounds in ionic liquids. The application of this acidic ionic liquid is studied in a new one-pot method for the synthesis of imidazole derivatives under solvent-free conditions. The advantages of this method are the reusability of the catalyst, high conversion, short reaction time, and simple experimental procedure.

A novel, acid catalyzed multicomponent one-pot synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazole compounds derived from aromatic aldehydes, 9,10-phenanthrenequinone and ammonium acetate under ultrasonic irradiation is reported. A wide range of aromatic aldehydes readily undergo condensation with 9,10-phenanthrenequinone and ammonium acetate under optimized conditions to afford the desired imidazoles of good purity in excellent yields.
