Procedure

100 g of N-bromosuccinimide are added to the mixture of 250 ml of α-methylstyrene and 40 ml of carbon tetrachloride. The resulting mixture is heated to reflux for 5 min. and cooled in an ice-water bath. Filtration and concentration give the desired compound, 1-bromo-2-phenylpropene, and an isomer thereof (65:35).
