Synthesis of substituted 1-acyl-1′-biphenylylferrocenes. Crystal structures of 4-bromo-4′-ferrocenylbiphenyl and 1-(4′-cyanobiphenyl-4-yl)-1′-((S)-3-methylpentanoyl)ferrocene
Arylation of ferrocene with substituted biphenyldiazonium tetrafluoroborates afforded 4-bromo-, 4-nitro-, and 4-cyano-4'-ferrocenylbiphenyls. 4-Nitro- and 4-cyano-4'-ferrocenylbiphenyls were studied by X-ray diffraction analysis. In the crystals of 4-nitro-4'-ferrocenylbiphenyl, the molecules are linked via stacking pi-pi interactions.

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.
