Subjects: *SUBSTITUTION reactions, *METHYL groups, *CARBONYL compounds, *ALDEHYDES, *KETONES, *BORIC acid, *SODIUM borohydride
Abstract: Abstract: Aldehydes or ketones were reacted with 2-(trimethylsilyl)-1,3-dithiane (1) and the products reduced to the corresponding dithianes using tetrafluoroboric acid and sodium borohydride. These sulfur containing compounds were reacted with bromine trifluoride under mild conditions (1–2min, 0°C) with a net result of replacing the carbonyls'' oxygen with the desired difluoromethyl moiety.
