    • A process for producing a bipyridinium compound represented by formula (4), the process comprises: reacting a bipyridine which may have a substituent with a halogenated (hetero)aryl compound represented by formula (1), so as to produce a N,N'-bis((hetero)aryl)-bipyridinium compound represented by formula (2); and reacting the N,N'-bis((hetero)aryl)-bipyridinium compound with an amine compound represented by formula (3), without subjecting the N,N'-bis((hetero)aryl)-bipyridinium compound to an isolation treatment, In formula, R represents a (hetero)aryl group; X represents a halogen atom; R 11 , R 12 , R 13 , R 14 , R 15 , R 16 , R 17 and R 18 each independently represents a hydrogen atom or a substituent; and R 1 represents a (hetero)aryl group which may have a substituent or an alkyl group, wherein a polyhydric alcohol is used as a reaction solvent.
    • 一种制备由式(4)表示的联吡啶鎓化合物的方法,该方法包括:使可具有取代基的联吡啶与由式(1)表示的卤代(杂)芳基化合物反应,以产生N,N' 双((杂)芳基) - 联吡啶鎓化合物; 并且使N,N'-双((杂)芳基) - 联吡啶鎓化合物与式(3)表示的胺化合物反应而不使N,N'-双((杂)芳基) - 联吡啶鎓化合物进行分离 式中,R表示(杂)芳基; X表示卤原子; R 11,R 12,R 13,R 14,R 15,R 16,R 17和R 18各自独立地表示氢原子或取代基; R 1表示可以具有取代基的(杂)芳基或烷基,其中使用多元醇作为反应溶剂。
