Bismuth(III)–SiO2 catalyzed synthesis of polysubstituted imidazoles with the participation of azaaryl derivatives of aniline in four-component reactions
Bismuth(III)–SiO2 catalyzed synthesis of polysubstituted imidazoles with the participation of azaaryl derivatives of aniline in four-component reactions
A series of novel polyaromatic derivatives of imidazole were synthesized by Bi(III) nitrate–SiO2 catalyzed four-component reactions of benzil, ammonium acetate, aromatic aldehydes, and N -heterocyclic derivatives of aniline under solvent-free conditions.
