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.

Acylation of 4-bromo- and 4-cyano-4′-ferrocenylbiphenyl with alkanoyl chlorides afforded the corresponding 1-acyl-1′-biphenylylferrocenes in ∼20% yields. X-ray diffraction study of the above-mentioned bromo derivative and 1-(4′-cyanobiphenyl-4-yl)-1′-((S)-3-methylpentanoyl)ferrocene demonstrated that these ferrocenylbiphenyl derivatives crystallize in noncentrosymmetric space groups.

Cross-coupling reactions of bis(ferrocenyl)mercury with aryl- and heteroaryl iodides were shown to be easy and convenient for the synthesis of monoarylsubstituted ferrocenes in high yields. The highly selective substitution of iodine atom in iodobromoarenes by the ferrocenyl unit was demonstrated.

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.
