Synthesis of 3-(4-bromophenyl)-1-propene

Preparation of 3-(4-bromophenyl)-1-propene

A solution of 130 g. (1.08 moles) of allyl bromide in twice its volume of dry ether is added dropwise to an ethereal solution of p-bromo-phenylmagnesium bromide prepared from 1.0 mole (237 g.) of p-dibromobenzene and 27 g. (1.1 gram atoms) of magnesium. The mixture is then heated to reflux for 30 minutes, followed by the drop-wise addition of excess water to the cooled mixture. The ether is distilled off, and the residue is steam-distilled to remove the p-bromo-allylbenzene. The product is separated from the distillate, dried over calcium chloride, and distilled twice through a Vigreux column to give 128-130 g. of p-bromoallylbenzene, b.p. 95-96°/12 mm. The yield is 66% based on bromobenzene.
