4-Hydroxybiphenyl → 4-Allyloxybiphenyl

Participants

Reaction Steps

4-Phenylphenol 64 (25.5 g, 0.15 mol), allyl bromide (20.0 g, 0.165 mol) and K2CO3 (41.5 g, 0.15 mol) in 75 ml of dry DMF were stirred at room temperature overnight. The reaction mixture was diluted with 500 ml of diethyl ether and washed with water. The ether layer was washed with brine, dried and concentrated to give a lightly brown solid that was recrystallized from hexane to give 24.9 g of 4-allyloxy-biphenyl 65.
