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:[2]

SO2 + KF → KSO2F

This salt is then chlorinated to give sulfuryl chloride fluoride[3]

KSO2F + Cl2 → SO2ClF + KCl

Further heating (180 °C) of potassium fluorosulfite with the sulfuryl chloride fluoride gives sulfuryl fluoride.

Alternatively, sulfuryl chloride fluoride can be prepared without using gases as starting materials by treating sulfuryl chloride with ammonium fluoride or potassium fluoride in trifluoroacetic acid.[4]

SO2Cl2 + NH4F → SO2ClF + NH4Cl
