【摘要】 将2-羟乙氧乙基对甲苯磺酸酯与4,4′-联吡啶按物质的量比1∶10混合,加热到熔化,保温10 min,形成N-羟乙氧乙基-4,4′-联吡啶,收率88%;然后与α,α-′(二溴甲基)-2,2′-联吡啶按物质的量比2∶1混合,加热到熔化,保温10 min,形成标题化合物,收率82%。更多还原

【Abstract】 A mixture of 2-(hydroxyethoxy) ethyl toluensulfonate(1.0 mmol) and 4,4′-bipyridine(10.0 mmol) was heated to the melted state and the mixture was maintained at that temperature for 10 min to obtain N-(2-hydroxyethoxy)ethyl-4,4′-bipyridinium at 88% yield,and reacted with α,α′-bis(bromomethyl)-2,2′-bipyridine under melted condition for 10 min to give bipyridiniumdiol bridged by 2,2′-bipyridine.更多还原
