Fluorobis(phenylsulfonyl)methane Chemical Properties,Uses,Production
Description
Fluorobis(phenylsulfonyl)methane (FBSM), can be deprotonated under much milder basic conditions than those required for the deprotonation of fluoromethyl phenyl sulfone, and thus has been used as an excellent nucleophilic fluoromethylation reagent in many catalytic asymmetric reactions with allyl esters, imines, and α,β-unsaturated compounds. Stereoselctive nucleophilic substitution reaction between chiral alcohols and FBSM under Mitsunobu conditions gives the fluoromethylated products with full inversion of the configuration. Nucleophilic substitution reaction of epoxides and aziridines with FBSM gives the precursors of β-fluoromethylated alcohols and amines in high yields. As a carbon acid, FBSM can also be used in cross dehydrogenative coupling reaction.
Uses
