  • Synthesis of highly fluorinated aromatic compounds
    Patent number: 5026929
    Abstract: A process is disclosed for making a highly fluorinated aromatic compound by contacting a perfluorocycloalkane, such as perfluorodecahydronaphthalene, with a complex of a metal from Groups IA and IIA of the Periodic Table and an organic electron acceptor. The reaction is carried out in an organic solvent and under reducing conditions which are relatively moderate. Best results are obtained using a perfluorocycloalkane having 2-4 condensed rings and a complex of either sodium or lithium and benzophenone thereby making a perfluorinated condensed ring aromatic compound such as perfluoronaphthalene or perfluorophenanthrene.
