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.

)bicyclo[2.2.1]hept-5-en-2-alkoxides, which further undergo intramolecular cyclization to give the corresponding 2,3-dihydro-4-trifluoromethyl-5-X-furans. The corresponding alcohols (X = H, Cl) were isolated after quenching the reaction mixture at low temperature. The ring expansion process provides a simple synthetic procedure for the preparation of fluorinated norbornenes containing 2,3-dihydro-
