reaction of dichlorocarbene [generated by thermaldecomposition of trifluoro(trichloromethyl)silane] with hexafluorobut-2-yne; the 3,3-dichloro-compound is isomerised to the 1,3-dichloro-isomer by heat, light, or chemical catalysis, but conditions are described for the preparation of either pure cyclopropene. Treatment of either isomer with antimony pentafluoride gives solutions containing the chlorob
