  Interaction of perfluorinated α-fluorosulfatocarbonyl compounds with nucleophilic reagents

  摘要：

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

  Reactions of fluoroaliphatic α,β-unsaturated carbonyl compounds and perfluoro-2,7-dimethylocta-3,5-diene with electrochemically generated peroxydisulfuryldifluoride proceed to give both 1∶1 adducts and fluorosulfatodimerization products, whose formation is explained by generation of heteroallyl and allyl radicals due to the addition of a fluorosulfonyloxy radical to the sterically hindered vinyl carbon
