[(E)-1-bromoprop-1-en-2-yl]benzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

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). The resulting mixture is heated to reflux for 5 min. cooled in an ice-water bath Filtration and concentration
