Interaction of sulfofluoride group in the organofluorine compounds with silver oxide and carbonate

Abstract

For the successful use of these compounds in the modern membrane, catalytic, and other advanced technologies synthetic methods are required, which allow a consecutive utilization of the reactivity of sulfofluoride and fluorocarbonyl functions. In particular, when solving the problem of obtaining silver 2,2-difluoro-2(fluorosulfonyl)acetate, the reaction of this acid with silver oxide (method a) was examined assuming that sulfofluoride group will not be affected. However, the reaction of equimolar amounts of the starting compounds affords a mixture of the salts of sulfonic and carboxylic acids. Nonetheless, the synthesis of silver 2,2-difluoro-2(fluorosulfonyl)acetate was successfully performed by using the silver carbonate and carboxylic acid fluoride instead of the silver oxide and carboxylic acid.
