PROCEDURE

实验过程

A solution of bromine (24.4 g) in carbon tetrachloride (50 ml) was added slowly over a period of 2 hours 45 minutes to a vigorously stirred solution of 2-chloro-3,6-difluorotoluene (24.4 g) in carbon tetrachloride (150 ml) irradicated by a 200 watt tungsten lamp maintained at 0° C. The solvent was removed by evaporation under reduced pressure and the residual oil distilled to yield 2-chloro-3,6-difluorobenzyl bromide (29.7 g) b.p 96°-101°/0.7 cm Hg
