Carbenium ions electron-transfer equilibria

On the basis of analysis of typical byproduct spectra W. Dmowski postulated a mechanism for the reaction [139]. In aHF as solvent the SF, species is generated in a solvolytic equilibrium. The strongly electrophilic SF, ion adds to the carbonyl oxygen, making the a-carbon atom highly electrophilic. A fluorine atom is then transferred intramolecularly to the carbon and sulfonyl fluoride is expelled. The resulting resonance-stabilized (by r-donation from fluorine lone electron pairs) a-fluoro carbenium ion adds fluoride from ambient (FHF) ions (Scheme 2.64).
