Benzenesulfonyl bromide Usage And Synthesis

Uses

Benzenesulfonyl bromide can be used as a sulfonating reagent to produce sulfonamides and sulfones.

Preparation

Benzenesulfonyl bromide can be prepared by reaction of sodium benzenesulfonate with bromine in 98% yield.

storage

by analogy to Benzenesulfonyl Chloride, benzenesulfonyl bromide should be assumed to be an irritant and harmful by skin absorption and ingestion. Benzenesulfonyl bromide  is best used immediately following preparation and may be used in situ. The reagent is moisture sensitive and will react with nucleophilic solvents (e.g. alcohols), liberating HBr and therefore should be stored under  an inert atmosphere. Use in a fume hood.
