The gas-phase copyrolysis of tetrafluoroethylene with buta-1,3-diene in a flow reactor at 495–505 °C produces 3,3,4,4-tetrafluorocyclohex-1-ene, which selectively converted to 1,2-difluorobenzene or 1-chloro-2,3-difluorobenzene. The latter can be converted to 2-chloro-3,4-difluoronitrobenzene, 2,3,4-trifluoronitrobenzene, 2,3-difluoro-6-nitrophenol, or 2-chloro-3-fluoro-4-nitrophenol via nitration, fluorodechlorination, and hydrolysis reactions.
