Versuchsvorschrift
In this instance the 2-fluoro-4-methylbiphenyl was heated to 140° to 170° C. with a heating mantle and under irradiation with light without a solvent while one equivalent of Br2 was added dropwise. Subsequent NMR analysis showed the starting material:monobromide:dibromide ratio to be 25:58:18.
