Reagent and procedure for the synthesis of organic derivatives oxisulfurados and fluorinated.

摘要

The invention relates to a reagent useful for the synthesis of organic derivatives OXISULFURADOS and fluorinated by reaction with a sulfur oxide, PARTICULARLY sulfur dioxide, characterized in that it comprises: A) an acid fluorocarboxylic OF FORMULA EA-CF {SUB 2} -COOH WHERE EA represents an atom or group that draws electrons, at least partially salified by a cation organic or MINERAL, b) an aprotic polar solvent, AND THE FACT THAT THE CONTENT CARRIED IN PROTON releasable for its various components, including impurities, is what SAME joined the MOLAR CONCENTRATION HALF OF INITIAL fluorocarboxylic said acid. This reagent can be implemented by heating to form sulfinic or sulfonic acids FLUORINATED.
