Versuchsvorschrift

Aniline (1.0 g) was dissolved in tert-butylmethyl ether (15 ml) and water (15 ml), and added with undecafluoroiodocyclohexane (5.5 g), sodium dithionite (2.3 g), sodium hydrogen carbonate (1.1 g) and tetrabutylammonium hydrogen sulfate (0.46 g) in order. The resulting mixture was stirred vigorously at room temperature for 18 hours. After separating the reaction solution, the aqueous phase was extracted twice with ethyl acetate. The organic phases were combined and washed with 2N hydrochloric acid and sodium hydrogen carbonate solution in order, and dried over anhydrous magnesium sulfate, The drying agent (anhydrous magnesium sulfate) was removed by filtration and the solvent was distilled off under the reduced pressure. The residue was purified by column chromatography to obtain 4-(undecafluorocyclohexyl)aniline (2.7 g, yield 68%).
