Abstract
The preparation of a fluorous super Brønsted acid catalyst,
4-(1H ,1H -perfluorotetradecanoxy)-2,3,5,6-tetrafluorophenylbis(trifluoromethanesulfonyl)methane
(3d ), is described. The fluorous catalyst 3d can be recycled by using liquid/solid
phase separation without fluorous solvents. A perfluorocarbon solvent
is not essential for fluorous biphasic catalysis.
Key words
Brønsted acid - fluorous catalyst - ponytail - fluorous biphasic catalysis - superacid

5b Pyridine was more effective
as a solvent in the para -substitution
reaction of a lithium salt of 1 with sodium
alkoxides. In contrast, this reaction did not occur smoothly in
diethyl ether, which was effective in the para -substitution
reaction with alkyllithiums.

7 In the case of the esterification,
the resultant solution was concentrated under reduced pressure,
and the crude compounds were diluted in hexane to precipitate 3d . Thus, 3d was
recovered by filtration.
