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.
