摘要
Audience participation: Fluorosulfinic acid, which is not known in its free state, was isolated in its protonated form as the [FS(OH)2] +[SbF6]- salt. It was prepared by addition of SO2 to the superacid HF/SbF5. SO2 has been used as a solvent for HF/SbF5 superacid systems for over 40 years. Only now is it shown that when SO2 is added to HF/SbF5 the [FS(OH)2]+ ion (see structure) is formed in an equilibrium with the SO2SbF5 adduct.
