protocol for synthesis of variously substituted imidazole derivatives via multicomponent condensation of benzil, primary aromatic amine, substituted 1,3-diphenyl-1 H -pyrazole-4-carbaldehyde, and ammonium acetate in presence of 1-butyl-3-methyl-1-imidazolium tetrafluoroborate [BMIM][BF4] as catalyst under conventional reflux as well as microwaveirradiation condition. The one-pot synthesis, facile solvent-free
