Chromium oxide is a good catalyst for scrambling halogens among polyhaloaromatic compounds.Chloropentafluorobenzene and bromopentafluorobenzene disproportionate to hexafluorobenzene and the respective tetrafluorodihalobenzenes.Pentachloro- and pentafluoropyridines produce pyridines with intermediate numbers of both types of halogens.Cyano, trifluoromethyl and a single hydrogen can be present on the aromatic rings without interfering with the chemistry.
