Synthesis and Coordination Chemistry of Fluorinated Cyclopentadienyl Ligands

Abstract

AbstractThe incorporation of fluorinated substituents in cyclopentadienyl anions leads to distinct changes in the properties of the corresponding metal complexes, e.g., with regards to electrochemical properties or metal–ligand bonding energies. This review summarizes the synthetic challenges of the preparation and coordination of fluorinated cyclopentadienyl anions.1 Introduction2 Fluorinated Cyclopentadienyls3 Cyclopentadienyls with One CF3 Group4 Cyclopentadienyls with Four CF3 Groups5 Cyclopentadienyls with Five CF3 Groups6 Cyclopentadienyls with ‘Fluorous Ponytails’7 Cyclopentadienyls with C6F5 Groups8 Trends in Interaction Energies9 Conclusion
