Disulfuryl chloride fluoride (pyrosulfuryl chloride fluoride) is an inorganic compound of sulfur, chlorine, fluorine, and oxygen with the chemical formula S2O5ClF.[2] Structurally, it is the chlorofluorosulfuric acid analog of disulfuric acid, or the mixed anhydride of chlorosulfuric acid and fluorosulfuric acid.

Synthesis

Rapid heating of fluorosulfonic acid and cyanuric chloride:[3]

6HSO3F + (CNCl)3 → 3S2O5ClF + (HNCO)3 + 3HF

Also, a reaction of disulfuryl chloride (S2O5Cl2) on silver monofluoride (AgF) at 80-90 °C.[4]

Physical properties

Disulfuryl chloride fluoride is a colorless liquid.

The compound hydrolyzes in water.
