• <I>syn</I>- and <I>anti</I>-[0]Orthocyclo[2]orthocyclo[0](1,1′)ferrocenophan-7-enes were synthesized <I>via</I> an intramolecular reductive coupling of 1,1′-bis(<I>o</I>-formylphenyl)ferrocene with low valent titanium reagents, <I>syn</I>- and <I>anti</I>-[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[<I>o</I>-(bromomethyl)phenyl]ferrocene and 1,1′-bis[<I>p</I>-(bromomethyl)phenyl]ferrocene with butyllithium. The transannular π-electronic interactions between two aromatic rings in these compounds were examined on the basis of the NMR and electronic spectra.
