摘要
采用室温固相研磨的方法,4,4′-联吡啶与连有阻塞基的乙氧乙醇磺酸酯(或苄溴)反应,得到单取代的4,4′-联吡啶六氟磷酸盐(2),2再与α,α′-二(溴甲基)-2,2′-联吡啶反应,得到哑铃型化合物——2,2′-联吡啶桥连的双-4,4′-联吡啶六氟磷酸盐(3),收率约90%。2和3的结构经1HNMR,13CNMR和MS表征。
The dumbbell-shape compounds, quaternary ammonium salts （3） of 4,4＇-bipyridines bridged 2,2＇-bipyridine in yields of about 90%, were synthesized by solid grinding at room temperature from quaternary ammonium salts（2） of N-substituted 4,4＇-bipyridine which were prepared via the reaction of 4,4＇-bipyridine and tosylate （or benzyl bromide） containing stopper in yields of 60%～90%. The structures of 2 and 3 were characterized by ^1H NMR, ^13C NMR and MS.
