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.
