4-Bromobenzenesulfonyl Azide is a 1,3-dipolar reagent that undergoes cycloaddition to vinyl and alkynyl ethers^[1].

4-Bromobenzenesulfonyl Azide is prepared by the reaction of 4-Bromobenzenesulfonyl Chloride with excess Sodium Azide in a water-ethanol mixture^[2-3].

4-Bromobenzenesulfonyl Azide should be used in solution. Azides are prone to violent detonation upon thermal, electrical, and mechanical shock.
