An efficient one-pot approach for the preparation of 2,4,5-trisubstituted phenanthroimidazole derivatives is described. The three-component reaction between 9,10-phenanthraquinone, benzaldehyde derivatives, and ammonium acetate proceeds in the presence of SBA-Pr-SO3H as a nanoporous solid acid catalyst in short reaction times and good to excellent yields.
