reversible nucleophilic addition of a monofluorinated sulfone, α-fluoro-α-phenylthio-α-phenylsulfonylmethane (FTSM), to aldehydes has been developed, which allows the efficient synthesis of β-fluorinated carbinols with high diastereoselectivity. Control experiments showed that the fluorine substitution not only promotes the addition process, but also improves the diastereoselectivity.

A diastereoselective nucleophilicmonofluoromethylation of tert-butanesulfinyl aldimines with α-fluoro-α-phenylthio-α-phenylsulfonylmethane (FTSM) as the reagent has been developed, which affords α-monofluoromethyl amines in good to excellent yields with excellent stereocontrol on both the monofluoromethylated carbon and the neighboring sulfonyl-bearing fluorinated carbon. The racemic α-fluoro-α-p

Highly regioselective monofluorination of α-sulfonyl sulfides was successfully carried out using anodic oxidation to provide the corresponding α-fluorinated products in moderate yields. The fluorinated products would be versatile fluorine-containing building blocks.
