Sodium trifluoromethanesulfinate (CF3SO2Na) is the sodium salt of trifluoromethanesulfinic acid. Together with t-butyl hydroperoxide, an oxidant, this compound was found to be a suitable reagent for introducing trifluoromethyl groups onto electron-rich aromatic compounds by Langlois; this reagent is also known as the Langlois reagent. This reaction operates via a free radical mechanism. This reagent is also able to trifluoromethylate electron-deficient aromatic compounds under biphasic conditions. Zinc difluoromethanesulfinate, a related polymeric coordination complex, is able to introduce difluoromethyl groups (CHF2-) onto aromatic compounds under similar biphasic conditions as well. ==References== 〔
