Introduction of FeCp + to o-, m-, p-terphenyl and the structures of mononuclear and dinuclear complexes

Mononuclear and dinuclear arene complexes of o-, m-, and p-terphenyl were isolated. FeCp + was introduced to the central benzene in the mononuclear complexes, while they were introduced to the terminal benzenes in the dinuclear complexes. FeCp + complexes of o-, m-, and p-terphenyl were synthesized....

Description
Summary:Mononuclear and dinuclear arene complexes of o-, m-, and p-terphenyl were isolated. FeCp + was introduced to the central benzene in the mononuclear complexes, while they were introduced to the terminal benzenes in the dinuclear complexes. FeCp + complexes of o-, m-, and p-terphenyl were synthesized. Mass spectra showed the existence of mononuclear and dinuclear complexes in all isomers. Mononuclear and dinuclear complexes were separated by using the difference in solubility to CH 2Cl 2. X-ray structural analyses revealed that the FeCp + was introduced to the central benzene in the mononuclear complexes, while they were introduced to the terminal benzenes in the dinuclear complexes. 57Fe Mössbauer spectra showed arene-type Fe II doublet.
