Versuchsvorschrift

A solution of 4-fluorophenylacetic acid (9.7 g), N-bromosuccinimide (11.2 g) and azobisisobutyronitrile (AIBN, 0.2 g) in carbontetrachloride (100 ml) was reluxed for 2 hours. After cooling it was filtered through Celite® and the filtrate was evaporated to give an oily residue of α-bromo-4-fluorophenylacetic acid, which was used for next step without purification.
