CoFe_2O_4 magnetic catalyst assisted a facile one-pot multicomponent construction of 2,4,5-trisubstituted-1H-imidazole derivatives

摘要

The 2,4,5-trisubstituted imidazole derivatives have been synthesized via one-pot condensation of benzil aromatic aldehydes and ammonium acetate catalyzed by CoFe_3O_4 magnetic catalyst. All products were obtained in good yields. The CoFe_3O_4 magnetic catalyst can be recycled easily and reused without significant decrease in catalytic ability.
