2,6- and 6,6- difluorinated α-substituted cyclohexenes have been prepared by the action of morpholinosulfur trifluoride on the corresponding cyclohex-2-enones under thermal conditions. The overall efficiency of this process has been significantly improved by the application of ultra high pressure (10-19Kbar). Investigations into the scope of this methodology have resulted in the preparation of the novel fluorinated compounds: 6,6-difluorolimonene and 3,3-difluoro-4-cholestene.
