反応手順
4′-Fluorobiphenyl (5 g) was dissolved in chloroform (100 mL) at room temperature. Chlorosulfonic acid (5 g) was added dropwise and stirring was continued for a further 4 hours, after which the solvent was allowed to slowly evaporate until precipitation was seen. The mixture was left to recrystallised overnight and the solid was collected by filtration. Further crops of crystals were collected from the filtrate.
