intermediates in nucleophilic fluoroalkylation reactions. Although frequently discussed, the origin of the fluorine effect on the reactivity of α‐fluorinated CH acids has remained largely unexplored. We have now investigated the kinetics of a series of reactions of α‐substituted carbanions with reference electrophiles to elucidate the effects of α‐F, α‐Cl, and α‐OMe substituents on the nucleophilic reactivities

Anodic alpha-alkoxylation of sulfides was remarkably promoted in the presence of fluoride ions: When Et3N.3HF was used as a supporting electrolyte, simple alkyl phenyl sulfides and sulfides bearing weak electron-withdrawing groups underwent anodic alkoxylation via fluorosulfonium ions as key intermediates in a unique Pummerer-type mechanism with reasonable or high yields for the first time.
