The reaction of 3,4,5,6-tetrahydrophthalic anhydride 1 with sulphur tetrafluoride and hydrogen fluoride was investigated under variable temperatures.At 80 deg C difluorolactone 2 was obtained in almost quantitative yield while at 120-150 deg C a mixture of compound 2, tetrafluoroether 3, acid fluoride 4 and bis(trifluoromethyl)cyclohexene 5 was formed.At higher reaction temperatures dehydrogenation of the cyclohexene ring occurred to give bis(trifluoromethyl)benzene 6 as the main product. sulphur tetrafluoride, fluorination of tetrahydrophthalic anhydride, fluorocyclisation, tetrafluoroethers, dehydrogenation of cyclohexene ring
