摘要：
In the present invention, a target alkoxycarbonylfluoroalkanesulfonic acid salt is obtained by using a halofluoroalkanoic acid ester as a starting raw material, sulfinating the halofluoroalkanoic acid ester in the presence of an amine (as a first step), and then, oxidizing the resulting sulfination product (as a second step). Further, an alkoxycarbonylfluoroalkanesulfinic acid onium salt, which is useful as a photoacid generator, is obtained by salt exchange reaction of the alkoxycarbonylfluoroalkanesulfonic acid salt.
