atoms and three 2,2′‐bipyridine (bpy) units is described. Starting with the bpy‐centred ligands 5,5′‐bis[3‐(1,4‐dioxahept‐6‐enylphenyl)]‐2,2′‐bipyridine and 5,5′‐bis[3‐(1,4,7‐trioxadec‐9‐enylphenyl)]‐2,2′‐bipyridine, we have applied Grubbs’ methodology to couple the terminal alkene units of the coordinated ligands in [FeL3]2+ complexes. Hydrogenation and demetallation of the iron(II)‐containing macrocyclic
描述了有机大环的模板化合成,该大环包含最多96个原子的环和三个2,2'-联吡啶(bpy)单元。从以bpy为中心的配体开始5,5'-bis [3-(1,4-dioxahept-6-苯基苯基)]-2,2'-联吡啶和5,5'-bis [3-(1,4, 7‐trioxadec‐9‐enylphenyl)]-2,2'‐联吡啶,我们已应用Grubbs方法将[FeL 3 ] 2+配合物中配位体的末端烯烃单元偶联。含铁(II)的大环络合物的加氢和脱金属作用导致大型有机大环化合物的分离。后者结合Ru(bpy)2 }单元,得到具有环外钌(II)域的大环配合物。复数[Ru(bpy)2(L)] 2+(作为六氟磷酸盐分离),其中L = 5,5'-双[3-((1,4,7,10-四氧杂环丁酸酯-12-苯基苯基)]-2,2'-联吡啶经历分子内闭环复分解以产生保留了环外Ru(bpy)2 }单元的大环。后一个大环中的聚(
