Data are summarized on the methods of synthesis of polyfluoroalkoxysulfur trifluorides and polyfluoroalkoxy(dialkylamino)sulfur difluorides which are intermediate products in fluorination of alcohols with sulfur tetrafluoride and dialkylaminosulfur trifluoride. Their thermal and chemical transformations are also discussed.

It has been established that the fluorination of 3β-hydroxy-Δ5,7-steroids, unlike that of 3β-hydroxy-Δ5-steroids, does not lead to the formation of 3β-fluoro derivatives. The reaction products are 3α,5α-cyclo-Δ6,8(14) compounds. Consequently, to obtain the 3β-fluoro derivatives of provitamins D — 7-dehydrocholesterol and ergosterol — the 5,7-diene system was first protected by the formation of a cyclo-adduct with 4-phenyl-1,2,4-triazoline-3,5-dione after which the adduct was fluorinated with morpholinosulfur trifluoride to the 3β-fluoro adduct, and then the 5,7-double bonds were regenerated by treating the adduct with a solution of sodium methanolate in methanol.
