An efficient and metal-free method for exclusively regioselective construction of aliphatic sulfonyl fluoride moiety at the C4 position of 1,2,3-triazole ring was successfully developed from the cycloaddition between but-3-ene-1, 3-disulfonyl difluoride (BDF) and organic azides in up to 95 % isolated yield.
