A new Lewis acid - aluminum chlorofluoride - was demonstrated to be an effective catalyst for the isomerisation of fluoroolefins, polyfluorinated epoxides and cyclopropanes.At ambient temperature this catalyst converts perfluorobutadiene-1,3 into perfluorobutyne-2 and perfluoro(4-methylpentene-2) into perfluoro(2-methylpentene-2) in nearly quantitative yield.At 100 deg C, aluminum chlorofluoride causes the cleavage of perfluorinated tertiary amines. - Keywords: Electrophilic reactions; Fluorocarbons; Aluminum chlorofluoride; Lewis acid; NMR spectroscopy
ELECTROPHILIC ISOMERIZATION OF SUBSTITUTED PERFLUOROCYCLOPROPANES UNDER THE EFFECT OF SbF5

Perfluoro(alkoxycyclopropanes) are isomerized on heating in the presence of SbF5 into perfluoro(2-alkoxypropylenes), while perfluoro(alkylcyclopropanes) are isomerized into the corresponding internal fluoroolefins under the effect of SbF5.
Fluorosulfonation. Insertion of Sulfur Trioxide into Allylic C-F Bonds

Insertion of sulfur trioxide into allylic C-F bonds of both terminal and internal fluoro olefins is shown to form the most stable olefinic products.A mechanism involving fluoroallyl cations as intermediates is proposed.State-of-the-art ab initio calculations of the ground-state energies for two isomeric unsaturated fluoro ethers establish the slightly greater stability (5.7 kcal/mol) of a vinyl ether over the corresponding fluoro olefin.A description of the optimized geometries of these molecules is also presented.
