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.

An efficient, magnetically separable catalyst was synthesized by immobilization of Preyssler heteropoly acid (HPA) on Ni0.5Zn0.5Fe2O4 magnetite nanoparticles (MNPs) coated with hydroxyapatite (HA). The catalyst was characterized by scaning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), FT-IR, energy dispersive spectroscopy (EDS), and TGA. Activity of this catalyst was tested in the synthesis of imidazole derivatives via one-pot three-component condensation of [9,10]-phenanthraquinone with aryl aldehydes and ammonium acetate at room temperature under 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 rapid, efficient, and novel methodology for the synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazole derivatives, catalyzed by bis[N-(3,5-dicumylsalicylidene)-2',6'- fluoroanilinato]zirconium(IV) dichloride under ultrasonic irradiation at room temperature, is reported. A range of substituted imidazoles was synthesized in excellent yields from one-pot reaction of aromatic aldehydes, 9,10-phenanthrenequinone, and ammonium acetate. The remarkable features of this new procedure are introducing a new one-pot method for synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazoles, high conversion, short reaction time, and simple experimental and workup procedure.

experimental part, p. 79 - 81 (2011/10/02)
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.
