Title:
METHOD FOR PRODUCING ALKOXYCARBONYLFLUOROALKANESULFONIC ACID SALT
Document Type and Number:
WIPO Patent Application WO/2010/050392
Kind Code:
A1
Abstract:
An aimed alkoxycarbonylfluoroalkanesulfonic acid salt is obtained by using a halofluoroalkanoic acid ester as a starting raw material, and by sulfinating the ester in the presence of an amine (step 1) and then oxidizing the resulting product (step 2).  By salt exchanging the thus-obtained alkoxycarbonylfluoroalkanesulfonic acid salt (step 3), there can be obtained an alkoxycarbonylfluoroalkanesulfonic acid onium salt which is useful as a photoacid generator.
