Participants

Reaction Steps

19 g of 4'-ethyl-4-benzoyl-biphenyl, 12.4 g of N-bromosuccinimide and 0.12 g of azaisobutyronitrile in 400 mL of carbon tetrachloride were heated to boiling under reflux for 1.5 hours. After filtering off the precipitated material the solution was evaporated and the residue was recrystallized from cyclohexane. There were obtained 20.7 g (85%) of 4'-(1-bromo-ethyl)-4-benzoylbiphenyl as a colorless solid with a m.p. of 132°-134° C.
