[Uses]

Ethenesulfonyl fluoride can be used as a reactant to synthesize:
  • β-Arylethenesulfonyl fluorides via palladium(II) acetate-catalyzed Heck-Matsuda reaction with arenediazonium tetrafluoroborates.
  • Bisalkylsulfonyl fluoride(BSF) monomers via Michael addition reaction with amines/anilines. BSF monomers are applicable in the synthesis of polysulfonates.
  • Cyclobutane-fused pyridinyl sulfonyl fluorides by photocatalytic [2 + 2] cycloaddition with pyridones or isoquinolones.
