Sulfuryl chloride fluoride is a chemical compound with the formula SO2ClF. It is a colorless, easily condensed gas. It is a tetrahedral molecule.

Liquified sulfuryl chloride fluoride is employed as a solvent for highly oxidizing compounds.[1]

Preparation

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.

KSO2F + SO2ClF → SO2F2 + KCl + SO2

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
