In multi-step reaction sequences the precatenanes 23b, c are synthesised.After breaking the chemical bonds between the aromatic nuclei and the bridge head atoms of the double bridged system the -catenanes 25 b, c are obtained.The 13C NMR and mass spectra of the precatenanes and catenanes are discussed.
