Due to relatively high boiling point (-10 C) and low vapor pressure (8 bar at 60 C), sulfur dioxide (SO2) can be easily liquefied and handled in its liquid state. Liquid SO2 is one of the few polar solvents that possess Lewis acid properties. Besides, both organic and inorganic substances readily dissolve in liquid SO2 due to its high dipole moment (1.6 D). All these facts make liquid SO2 a unique solvent for organic synthesis, especially, for transformations involving charged intermediates.
