Abstrakt: syn- and anti-[0]Orthocyclo[2]orthocyclo[0](1,1')ferrocenophan-7-enes were synthesized viaan intramolecular reductive coupling of 1,1'-bis(o-formylphenyl)ferrocene with low valent titanium reagents, syn- and anti-[0]Orthocyclo[2]orthocyclo[0](1,1')ferrocenophanes and [0]paracyclo[2]paracyclo[0](1,1')ferrocenophane were prepared by the reaction of 1,1'-bis[o-(bromomethyl)phenyl]ferrocene and 1,1'-bis[p-(bromomethyl)phenyl]ferrocene with butyllithium. The transannular p-electronic interactions between two aromatic rings in these compounds were examined on the basis of the NMR and electronic spectra.
