Chemical compound
Sulfuryl chloride fluoride is a chemical compound with the formula SO2 ClF. 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 → KSO2 F
This salt is then chlorinated to give sulfuryl chloride fluoride[ 3]
KSO2 F + Cl2 → SO2 ClF + KCl
Further heating (180 °C) of potassium fluorosulfite with the sulfuryl chloride fluoride gives sulfuryl fluoride .
KSO2 F + SO2 ClF → SO2 F2 + 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]
SO2 Cl2 + NH4 F → SO2 ClF + NH4 Cl
