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; R11, R12, R13, R14, R15, R16, R17 and R18 each independently represents a hydrogen atom or a substituent; and R1 represents a (hetero)aryl group which may have a substituent or an alkyl group, wherein a polyhydric alcohol is used as a reaction solvent.
生产一种由公式(4)表示的双吡啶化合物的方法,该方法包括:将可能具有取代基的双吡啶与由公式(1)表示的卤代(杂)芳基化合物反应,以产生由公式(2)表示的N,N'-双((杂)芳基)-双吡啶化合物;并将N,N'-双((杂)芳基)-双吡啶化合物与由公式(3)表示的胺化合物反应,而无需对N,N'-双((杂)芳基)-双吡啶化合物进行分离处理。在公式中,R代表(杂)芳基;X代表卤原子;R11、R12、R13、R14、R15、R16、R17和R18分别独立地代表氢原子或取代基;R1代表可能具有取代基或烷基的(杂)芳基,其中多羟基醇用作反应溶剂。
