Abstract
Abstract The reaction of hydrogen atoms with trifluoroethylene has been studied at room temperature by using the mercury photosensitized decomposition of hydrogen as the source of hydrogen atoms. Product analyses using gas chromatography and 1H and 19F NMR spectroscopy confirmed the 1,2-migration of a fluorine atom in the CH2F\dotCF2 radical produced by the addition of a hydrogen atom to trifluoroethylene. The rate constant of the migration was estimated to be 2×1010 s−1 from the pressure dependence of the five kinds of hexafluorobutanes produced. NMR parameters for these fluorinated compounds were determined.
