α-Perfluorosulfatoperfluorocarbonyl compounds interact with alkaline metals halogenides to form the corresponding α-halo derivatives as a result of the direct nucleophilic substitution of the FSO3 group.Through the action of halogenide anions on perfluorinated α,β-bis-fluorosulfatocarbonyl compounds, substitution by halogen of the FSO3 group in the α-position to the carbonyl takes place.However, the FSO3 group in the β-position is cleaved, which allows α-substituted β-dicarbonyl derivatives to be obtained.
