A general and regioselective metal-free cycloaddition of organic azides to a hitherto underexplored bromovinylsulfonyl fluoride building block provides 4-fluorosulfonyl 1,2,3-triazoles. This reaction was extended to the synthesis of various sulfonates, sulfonamides, and sulfonic acid derivatives of triazoles.
