A wide range of per- and polyfluorinated aromatics (21 examples), including C6F6, C6F5CF3, C6F5CN, and C6F5NO2, were defluorinated with high conversions and high turnover numbers.

  The paper reports the use of new catalysts - alkaline metal fluorides in graphite of the general formula C8MF, where M=Li, Na, K, Rb or Cs, in the reactions of polyfluoroaromatic compounds with aromatic OH-acids and piperidine. These compounds are shown to have a high activity in the above processes, exceeding that of similar free fluorides of alkaline metals.
