Title:
2-(アルキルカルボニルオキシ)-1,1-ジフルオロエタンスルホン酸塩類およびその製造方法
Document Type and Number:
Japanese Patent JP5347371
Kind Code:
B2
Abstract:
By using an organic base when a carboxylic acid bromodifluoroethyl ester is sulfinated by using a sulfinating agent, there is obtained 2-(alkylcarbonyloxy)-1,1-difluoroethanesulfinic acid ammonium salt. By oxidizing the 2-(alkylcarbonyloxy)-1,1-difluoroethanesulfinic acid ammonium salt, there is obtained 2-(alkylcarbonyloxy)-1,1-difluoroethanesulfonic acid ammonium salt. By using the 2-(alkylcarbonyloxy)-1,1-difluoroethanesulfonic acid ammonium salt as a raw material and exchanging it into an onium salt directly or through saponification/esterification, there can be obtained a 2-alkylcarbonyloxy-1,1-difluoroethanesulfonic acid onium salt.
