Bismuth(III){SiO2catalyzed synthesis of polysubstituted imidazoles with theparticipation of azaaryl derivatives of aniline in four-component reactions

Abstract

A series of novel polyaromatic derivatives of imidazole were synthesized by Bi(III) nitrate{SiO2catalyzedfour-component reactions of benzil, ammonium acetate, aromatic aldehydes, andN-heterocyclic derivatives of anilineunder solvent-free conditions.
