The synthesis of new unsymmetrical and symmetrical macrocycles based on 2,2′-bipyridine units bearing two or four phenyl groups at the 6 and 6′ positions was achieved by an oxidative coupling reaction using 1,2-dibromoethane and organolithium derivatives of bipyridine. Among all new compounds prepared, two of them were structurally analysed in the solid state by X-ray diffraction.
通过使用1,2-二溴乙烷和联吡啶的有机锂衍生物进行氧化偶合反应,可以合成基于在6和6'位置带有两个或四个苯基的2,2'-联吡啶单元的新的不对称和对称大环。在制备的所有新化合物中,通过X射线衍射对其中两个在固态下的结构进行了分析。
