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