In this work,three component condensation of [9,10]-phenanthraquinone with benzaldehyde and ammonium acetate and nano Perovskites catalyst La0.5Pb0.5MnO3(NP-LPMO) was evaluated using a multicomponent reaction of phenanthroquinone,aromatic aldehydes and ammonium acetate for preparation of imidazole derivatives. This reaction done under reflux conditions  and  compare with reaction with reaction in solvent-free reaction.
