A Novel Hydrodechlorinative Dimerization of Chlorofluorocarbons over Supported Ni Catalysts

1,1,1-Trichloro-2,2,2-trifluoroethane or 1,1-dichloro-1,2,2,2-tetrafluoroethane, both of which have CF3 group, dimerizes over supported Ni catalysts at an elevated temperature (723 K) into corresponding C4-compounds in good to moderate yields.

FLUORINATION OF POLYHALOGENATED UNSATURATED COMPOUNDS WITH VANADIUM PENTAFLUORIDE

Vanadium pentafluoride reacts with polyfluorinated and polychlorinated olefins, alkadienes, cycloalkenes and cyclodienes in CFCl3 or without a solvent at -25 deg C to 100 deg C, forming products of addition of two fluorine atoms across the C=C bond.

REACTION OF POLYHALOGENATED UNSATURATED COMPOUNDS WITH VANADIUM PENTAFLUORIDE

Terminal polyhalogenoalkenes are fluorinated by vanadium pentafluoride at -20 to -30 deg C, whereas internal polyfluoroalkenes only react with vanadium pentafluoride when heated. 2-Chloropentafluoro-1,3-butadiene adds fluorine atoms predominantly at positions 1,4 under the influence of vanadium pentafluoride, but only the isomeric tetrafluorohexachlorobutanes are formed from perchloro-1,3-butadiene.Fluorination of perfluoroallylbenzene and perfluoro-β-methylstyrene takes place more rapidly in the side chain than in the aromatic ring.

Reaction of Bistrifluoromethylaminosulphenyl Chloride with Fluoro-olefins and Hexafluorobut-2-yne under Free-radical Conditions

Reaction of bistrifluoromethylaminosulphenyl chloride with unsymmetrical fluoro-olefins in daylight or under photochemical conditions gives both possible 1:1 adducts (ca. 1:1) arising from homolytic fission of the S-Cl bond.Addition to octafluorobut-2-ene and hexafluorobut-2-yne gives mixtures of the syn- and anti- adducts.
