Some ferrocenophanes, in which the two cyclopentadienyl rings are linked by biphenyl rings, have been synthesized via intramolecular reductive coupling of the corresponding formyl compounds with a low-valent titanium reagent. The structures of these cyclophane compounds were determined by IR, NMR, and UV spectra analyses. Transannular π-electronic interactions between the two biphenyl rings were examined

The application of bis(ferrocenyl)mercury as a source of ferrocenyl group in Pd-catalyzed reactions with aryl halides, acid chlorides and electrophilic alkynes has been demonstrated. The formation of dimethyl-(Z)-2,3-di(ferrocenyl)-2-butenedioate in Pd-catalyzed addition of bis(ferrocenyl)mercury to dimethylacetylenedicarboxylate has been confirmed by X-ray analysis.
