実験手順
A solution of 4-(1,1,2,2-tetrafluoroethoxy)toluene (6.73 g, 32.3 mmol), N-bromosuccinimide (5.75 g, 32.3 mmol) and 2,2-azobis(isobutyronitrile) (0.2 g) in carbon tetrachloride (30 ml) was heated under reflux for 0.5 hr. After cooling the reaction solution to room temperature, the white precipitate as removed by filtration and the precipitate was washed with diethyl ether. The solvent of the collected filtrate was evaporated under reduced pressure to give a crude product of 4-(1,1,2,2-tetrafluoroethoxy)benzyl bromide as a pale-yellow liquid.
