- Perfluorinated cyclic and acyclic keto-enol systems: A remarkable contrast
-
Recent reports from this laboratory have revealed that highly fluorinated 4- and 5-membered-ring enols are comparable in stability to, or more stable thermodynamically than, the corresponding ketones, even in non-Lewis-basic media. Work on perfluorinated

- REACTION OF POLYFLUORINATED DERIVATIVES OF BENZENE CONTAINING HYDROGEN ATOMS IN THE SIDE CHAIN WITH VANADIUM PENTAFLUORIDE
-
The treatment of C6F5R (R=CH3, CH2F, CHF2) compounds with vanadium pentafluoride at -25 to -30 deg C leads to a 1-R-heptafluoro-1,4-cyclohexadienes, 1-R-nonafluorocyclohexenes, and products form fluorination of the side chain.Fluorination of the anisole derivatives C6F5OCH3 and C6F5OCHF2 only takes place in the aromatic ring.
