Abstract:

The pyrolysis of perfluoroolefin oxides has been studied by gas chromatography/mass spectrometry at 400-700-degrees-C, in a current of He (1:10 dilution, contact time 1 sec). For oxides containing a terminal CF2 group, the sole degradation route is through the elimination of difluorocarbene. Pyrolysis of symmetrical disubstituted oxides results in the elimination of a perfluoroalkylfluorocarbene, which subsequently isomerizes to the corresponding perfluoroolefin. In the pyrolysis of unsymmetric disubstituted oxides the elimination of perfluoroalkylfluorocarbenes occurs by both of the possible routes. Trisubstituted oxides eliminate bis-perfluoroalkylcarbenes. The decomposition of tetrasubstituted oxides proceeds along several directions concurrently.
