Sulfuryl chloride fluoride is the chemical compound with the formula SO2ClF. It is employed as a solvent for highly oxidizing compounds.
The laboratory-scale synthesis begins with the preparation of potassium fluorosulfite:[1]
- SO2 + KF → KSO2F
This salt is then chlorinated to give sulfuryl chloride fluoride:[2]
- KSO2F + Cl2 → SO2ClF + KCl
Further heating (180 °C) of potassium fluorosulfite with the sulfuryl chloride fluoride gives sulfuryl fluoride.
