N2 - Perfluoro-1,1-diphenylethane heated with SbF5 at 130 °C with further treatment of the reaction mixture with HF-pyridine and then with water, gave perfluorinated 9‐methylfluorene and 9-methyl-1,2,3,4-tetrahydrofluorene. Perfluoro-1,1-diphenylpropane under similar conditions formed perfluoro-9-ethylfluorene and perfluoro-9,9-dimethyl-1,2,3,4-tetrahydrofluorene. When perfluoroisobutylbenzene was heated with pentafluorobenzene in SbF5 medium at 130 °C, with further treatment of the reaction mixture with HF-pyridine and then with water, perfluoro-9-isopropylfluorene was obtained. Perfluorodiphenylmethane heated with SbF5, after treatment of the reaction mixture with water, gave perfluorobenzophenone; perfluorofluorene or its derivatives were not found in the mixture.
