[摘要]:Some new 4-(aryl)-2,6-di-2-naphthylpyridines and 4-(aryl)-2,6-di-2-thienylpyridines have been prepared through three-component condensation of 2-acetylnaphthalene or 2-acetylthiophene, aromatic aldehydes, and ammonium acetate in presence of 1-(4-sulfonylbutyl) pyridinium hydrogensulfate [(CH(2))(4)SO(3)HPy][HSO(4)], a Bronsted acidic ionic liquid as a green and reusable catalyst in solvent-free conditions. Also some new 4,4'-(1,4-phenylene)-bis-(2,6-di-aryl pyridine) was prepared. |
