A series of 4′-aryl-2,2′:6′,2′′-terpyridines have been prepared by the one-pot reaction of 2-acetylpyridine with aromatic aldehydes in the presence of ammonium acetate under microwave irradiation. This method has the advantages of shorter route, easier workup, shorter reaction time, higher yield and more environmentally friendly conditions, compared to the conventional ones.
通过在微波辐射下,
乙酸铵存在的条件下,2-乙酰
吡啶与芳香醛的一锅法反应,成功制备了一系列4'-芳基-2,2':6',2''-三联
吡啶。与传统方法相比,该方法具有步骤更短、操作更简便、反应时间更短、产率更高以及条件更环保等优点。
