Conclusions
-
1.
The existence of polyfluorinated cations as intermediates in reactions of polyfluorine-containing vinyl ethers with electrophilic reagents has been proved.
-
2.
13C and19F NMR parameters were obtained of cations and anions formed from 1-methoxyperfluoro-2-methyl-1-propene and 3-methoxyperfluoro-2-methyl-2-pentene.
-
3.
Perfluorinated acylium cation was obtained from the first time and was identified by13C and19F NMR methods.
