An improved electrochemical dimerization of a N-substituted pyridinium salt to its corresponding N,N'-disubstituted 4,4'-tetrahydrobipyridine in a flow cell at a high-surface-area cathode, employing an ion-exchange membrane divider and an alkaline catholyte solution. Isolation and recovery of the resultant product are reported in significant yields are reported without the use of an extracting solvent or corrosion or other additive either in the catholyte solution or in any subsequent operation.
在高表面积阴极的流动池中,采用离子交换膜分隔器和碱性阴溶液,改进了 N-取代吡啶鎓盐到其相应的 N,N'-二取代 4,4'-四氢联吡啶的电化学二聚反应。 据报道,在阴溶液或任何后续操作中,均无需使用萃取溶剂或腐蚀剂或其他添加剂,即可分离和回收所产生的产物,且产量可观。
