実験手順

A 500 mL round-bottom-flask equipped with an addition funnel, stirring bar, and gas inlet was charged with 4-bromo-biphenyl (50 g, 0.215 mol) and chloroform (200 mL) then purged with nitrogen. Chlorosulfonic acid (18 mL, 0.27 mol) was added dropwise to the solution from the addition funnel then stirred for 1 hour. The resulting precipitate was collected by vacuum filtration, washed with cold chloroform, and dried under vacuum to give 61.97 g of 4′-bromo-biphenyl-4-sulfonic acid (92% yield).
