  An ammonium hydroxyfluoroalkanesulfinate is obtained by using an organic base while sulfinating a bromofluoroalcohol with a sulfinating agent. An ammonium hydroxyfluoroalkanesulfonate is obtained by oxidizing the ammonium hydroxyfluoroalkanesulfinate. An onium fluoroalkanesulfonate is obtained by converting the ammonium hydroxyfluoroalkanesulfonate into an onium salt through esterification. This onium fluoroalkanesulfonate is useful as a photoacid generator in chemically amplified resists and the like.
