    摘要： Provided is a method of manufacturing a bipyridinium compound denoted by general formula (A). In general formula (A), Ar1 and Ar2 each independently denote an optionally substituted (hetero)aryl group, R3 and R4 each independently denote a substituent that may form a ring with a pyridine ring to which the substituent substitutes, m3 and m4 each independently denote an integer ranging from 0 to 4, X denotes a halogen atom or RSO3, and R denotes an optionally substituted aryl group or alkyl group. The method can manufacture a 4,4′-bipyridinium compound under mild reaction conditions in an integrated manner without separation of intermediates.

    摘要翻译： 提供一种制备由通式（A）表示的联吡啶鎓化合物的方法。 在通式（A）中，Ar 1和Ar 2各自独立地表示任选取代的（杂）芳基，R 3和R 4各自独立地表示可以与取代基取代的吡啶环形成环的取代基，m 3和m 4各自独立地表示 表示0〜4的整数，X表示卤素原子或RSO 3，R表示可以具有取代基的芳基或烷基。 该方法可以在温和的反应条件下以一体的方式制备4,4'-联吡啶鎓化合物，而不分离中间体。
