Stable fluoroaliphatic radicals containing functional groups: Synthesis and reactivity

β-Fluorosulphatoperfluoroalkyl radicals (3, 7 and 8) are obtained by the reaction of fluoroolefins (HFP trimer and dimer, and perfluoro-4,4-dimethylpent-2-ene, respectively) with (FSO3)2. The pure β-fluorosulphatotetrafluoroethylperfluorodiisopropylmethyl radical (3) has been isolated and converted to the perfluoroacetyldiisopropylmethyl radical (4) under the action of CsF. The reaction of radicals 3, 7 and 8 with SbF5 leads to the replacement of the FSO3 group by a fluorine atom. The ability of the FSO3 group in β-fluorosulphatoperfluoroalkyl radicals to play the role of a leaving group is explained by the stabilizing effect of the unshared electron on the adjacent carbocation centre.

Reactivity of fluorocarbon radicals in the low-temperature fluorination of unsaturated perfluorocarbons

Calorimetry and ESR spectroscopy were used to study the low-temperature fluorination (77-300 K) of unsaturated perfluorocarbons with fluorine. In the solid phase at 77-100 K (glassy or crystalline state) fluorination does not occur. On transition from glassy systems to the supercooled liquid state formation of molecular complexes in which fluorine is attached to the >C=C bond becomes possible. These complexes are stabilized on crystallization of the system; with a further increase in temperature, efficient addition of molecular fluorine takes place in the crystal phase. However, the addition of fluorine by a chain or carbene mechanism must not be ruled out for such systems. Thus, in the case of hexafluoropropene trimer, the addition proceeds as a chain reaction producing long-living free radicals at the initial stage.

Spectroscopic observation of charge transfer complex formation of persistent perfluoroalkyl radical with aromatics, olefin, and ether

Charge transfer interaction of a persistent perfluoroalkyl radical, perfluoro-3-ethyl-2,4-dimethyl-3-pentyl (PFR-1), with benzene and methyl substituted benzenes (toluene, m-xylene, mesitylene), 1-decene, and diethyl ether was investigated by UV-vis spect
