Hydrofluoroalkanesulfonic acids from fluorovinyl ethers

摘要

Hydrofluoroalkanesulfonates of the general formula R-O-CXH-CX₂-SO₃M, where R is selected from the group consisting of alkyl groups, functionalized alkyl groups, and alkenyl groups; X is selected from the group consisting of hydrogen and fluorine with the proviso that at least one X is fluorine; and M is a cation, are made by reacting fluorovinyl ether with aqueous sulfite solution. Organic onium hydrofluoroalkanesulfonates are useful as ionic liquids and photoacid generators.
