Hydrogenolysis of CF bonds in fluorinated aromatic hydrocarbons catalysed by nickel complexes

Abstract
Reactions of hexafluorobenzene, pentafluorobenzene, octafluoronaphthalene and pentafluoropyridine with the NiCl 2 –2,2 ’ -bipyridine (or 1,10-phenanthroline)–Zn reductive catalytic system in DMF (or DMA) in the presence of water or ammonium chloride resulted in the products of C–F bond hydrogenolysis.
