An improved preparation of 2,2′-bipyridine-6-carboxaldehyde 1 provides this compound in good yield for the further syntheses of oligo-(2,2′-bipyridyl)pyrazines 6–8, new ligands for supramolecular metallorganic complexes. According to 1H-NMR spectroscopic and X-ray crystallographic studies, the bis(2,2′-bipyridyl) compound 6 exists in a helical conformation in solution and in the solid state. The structure
改进的2,2'-联吡啶-6-甲醛1的制备为进一步合成低分子-(2,2'-联吡啶基)吡嗪6-8(超分子金属有机配合物的新配体)提供了良好的收率。根据1 H-NMR光谱和X射线晶体学研究,双(2,2'-联吡啶基)化合物6以螺旋构型存在于溶液中并且为固态。通过其晶体结构也证实了四(2,2'-联吡啶基)化合物8的结构。
