Abstract
A method for preparing fluoroalkanesulphinic acid esters is described. The preparation of esters of trifluoromethanesulphinic acid, commonly referred to as “triflinic acid,” is also described. A method for preparing a fluoroalkanesulphinic acid ester is also described wherein the method includes reacting a fluoroalkanesulphinic acid with an organic carbonate leading to the formation of a fluoroalkanesulphinic acid ester and carbon dioxide, which is removed during the reaction.
