p-Bromobenzenesulfonyl chloride → 4-Bromobenzene-1-sulfonyl fluoride

Participants

Reaction Steps

To a solution of 4-bromophenylsulfonyl chloride (2 g, 7.83 mmol) in acetonitrile (10 mL), was added fluoride on Amberlyst A-26 (Aldrich Chemical Company, 7.5 g, 21.6 mmol F−). After agitation for 5 hours at room temperature, the mixture was filtered. The solvent was removed under reduced pressure to give 4-bromophenylsulfonyl fluoride (1.5 g) (confirmed by IR spectroscopy).
