Preparation, Characterization, and Application of Preyssler Heteropoly Acid Immobilized on Magnetic Nanoparticles as a Green and Recoverable Catalyst for the Synthesis of Imidazoles
Javid,Khojastehnezhad,Pombeiro
, p. 3000 - 3005 (2018/02/21)
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 imidazolium-based acidic ionic liquid as an efficient and reusable catalyst for the synthesis of 2-aryl-1H-phenanthro[9,10-d]imidazoles

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.
