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.
