Va. Petrov et al., ELECTROPHILIC REACTIONS OF FLUOROCARBONS UNDER THE ACTION OF ALUMINUMCHLOROFLUORIDE, A POTENT LEWIS-ACID, Journal of fluorine chemistry, 77(2), 1996, pp. 139-142
A new Lewis acid - aluminum chlorofluoride - was demonstrated to be an
effective catalyst for the isomerization of fluoroolefins, polyfluori
nated 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 quantit
ative yield. At 100 degrees C, aluminum chlorofluoride causes the clea
vage of perfluorinated tertiary amines.
