Electrophilic isomerization of fluoroaliphatic oxygen-containing compounds
摘要:
An unusual electrophilic cyclization of fluorine-containing carbonyl compounds and alpha-oxides was discovered. Upon the action of SbF5, perfluorinated ketones, diketones, and alpha-oxides isomerize to oxolanes. This reaction proceeds with the obligatory participation of the terminal CF3 group.

Vicinal bis(fluorosulfato) perfluoroalkanes containing FSO3 groups in the middle of a fluorocarbon chain eliminate one or two molecules of sulfuryl fluoride under the action of SbF5, forming a mixture of isomeric alpha-fluorosulfato ketones and alpha-diketones.

2,3-Bis(fluorosulfato) perfluoroalkanes split under the action of CsF in the absence of solvents, giving a mixture of alpha-fluorosulfatoperfluoro ketones, perfluoroalkene sulfates, and perfluoro alpha-diketones. The occurrence of these reactions in solutions results mainly in the formation of oxides of the corresponding fluoroolefins or products of their conversions. The reactions carried out are the first examples of nucleophilic substitution at a secondary carbon atom in a perfluorinated saturated chain.

The electrolysis of fluorosulfonic acid in the presence of perfluoro-2-alkenes in an electrolyzer without a diaphragm results in the formation of a mixture of products, whose composition is determined by both the anodic and cathodic processes.

A study has been made of the electrochemical fluorosulfation of perfluoro-2-alkenes in the presence of halogens, leading to the formation of fluoroaliphatic vicinal fluorosulfatohalides. The reaction proceeds as a conjugate radical addition of peroxydisulfuryl difluoride and the halogen at the double bond of the olefin; the ratio of the resulting regioisomers is determined by steric factors.
