Sodium trifluoromethanesulfinate (CF₃SO₂Na) is the sodium salt of trifluoromethanesulfinic acid. Together with

This reagent is also able to trifluoromethylate electron-deficient aromatic compounds under biphasic conditions.^[2] Zinc difluoromethanesulfinate, a related polymeric coordination complex, is able to introduce difluoromethyl groups (CHF₂-) onto aromatic compounds under similar biphasic conditions as well.^[3]

With the use of DMSO as an oxidant, it provides an environmentally friendly way for the synthesis of β-trifluoromethyl alcohols from alkenes.^[4]
