1-Bromo-4-(prop-1-en-2-yl)benzene → 1-Bromo-4-isopropylbenzene

Participants

Reaction Steps

A 23.2 g quantity of p-bromo-α-methylstyrene (118 mmole), approximately 100 mg platinum oxide, and 150 ml absolute ethanol were shaken on a Paar Hydrogenator for four hours, beginning with an initial hydrogen pressure of 50 psi. The material was then filtered through a celite plug and the solvent removed by distillation at atmospheric pressure. The residue resulting was distilled using a water aspirator vacuum to produce 18.9 g (80.4% yield) of p-bromocumene, bp 88°-92° C.
