2-Phenylethyl bromide

(Redirected from 2-Phenylethylbromide)

2-Phenylethyl bromide is an organobromide with the formula C6H5CH2CH2Br. It is a colorless liquid, although older samples appear yellow. Analogous to the preparation of most 1-bromoalkanes, it is prepared by free-radical addition of hydrogen bromide to styrene. These conditions lead to anti-Markovnikov addition, giving the 1-bromo derivatives.[1]
