A new short and simple pathway to rigid, rod-shaped hydrocarbon skeletons, in particular of the oligo-bicyclo[2.2.2]octane type, is described. The key step consists of an electrochemical C-C bond coupling reaction between bridgehead positions of bi- and tricyclic carboxylic acids. Functional groups can be retained, they influence the yield of the C-C bond connection. In this way, otherwise difficult or laborious syntheses are shortened, and rigid, non-collapsable nano size spacer units are easily available. The optimized electrochemical procedures are described in detail.
描述了一种新的简短且简单的方法,以获得刚性、棒状的碳氢骨架,特别是寡碱基[2.2.2]八烷类型。关键步骤是二环和三环羧酸的桥头位置之间的电化学C-C键偶联反应。功能团可以保留,并且它们会影响C-C键连接的产率。通过这种方法,以往难以或繁琐的合成过程得以缩短,同时刚性、不可崩溃的纳米级间隔单元也变得容易获取。优化后的电化学程序进行了详细描述。
