Oxidativedimerization of terminal alkynes (Glaser coupling) triggered by spirofluorene derived macrocyclic phenanthroline–Cu complexes was implemented to synthesize a series of novel [2]rotaxanes. Size and structural variations among the components and their implications on the dynamic behaviour were investigated in detail through 1H and 19F NMR spectroscopy. Strong perturbations in the NMR spectra
由螺芴衍生的大环菲咯啉-铜配合物引发的末端炔烃的氧化二聚反应(格拉泽偶联)被用于合成一系列新型 [2] 轮烷。通过1 H 和19 F NMR 光谱详细研究了组分之间的尺寸和结构变化及其对动态行为的影响。具有低对称性的取代大环组分的轮烷的 NMR 光谱中的强烈扰动表明环组分沿轴组分的非对称分布。在一些 [2] 轮烷中,观察到环组分位于 1,3-二炔部分附近。
