Room-temperature fluorination of 1,1-diphenylethene with caesiumfluoroxysulphate in methylene chloride resulted in an addition elimination process, thus yielding 1, 1-diphenyl-2-fluoroethene, while in the presence of nucleophile containing species, i.e., hydrogen fluoride, methanol, or acetic acid, either vicinal difluorides, methoxy fluorides or acetoxy fluorides were formed.

Vicinal alkoxy fluorides are efficiently formed by room temperature reaction of phenyl substituted alkenes with commercially available 1-chloromethyl-4-fluoro-1,4-diazobicyclo[2.2.2]octane bis tetrafluoroborate (Selectfluor(TM) F-Teda BF4) in CH3CN in the presence of various alcohols. The reaction follows Markovnikov-type regioselectivity, while stereoselectivity in the case of phenyl substituted benzocyclenes strongly depends on the ring size and the structure of the alcohol.
