実験手順
A mixture of 2,3,5,6-tetrafluorotoluene (1.7 g), N-bromosuccinimide (1.9 g), dry carbon tetrachloride (10 ml) and benzoyl peroxide (0.01 g) was heated at the reflux temperature for 20 hours, cooled to the ambient temperature (ca.25° C.) filtered and the filtrate diluted with diethyl ether. The ethereal solution was washed with water, dried over anhydrous magnesium sulphate and concentrated by evaporation of the solvents to yield 2,3,5,6-tetrafluorobenzyl bromide as a mobile colourless oil.
