SO3F2

Sulfuryl fluoride, with the chemical formula SO2F2, is a colorless gas that is stable under normal conditions. It is a derivative of sulfuric acid where the hydroxyl groups have been replaced by fluorine atoms. The molecule has a tetrahedral geometry around the sulfur atom.

SO2F2 is produced by the reaction of sulfuryl chloride with potassium fluoride or by the fluorination of sulfur dioxide. It is often prepared in laboratory settings and has found some niche industrial applications, though its use is limited due to its reactivity and potential hazards.

The compound is a strong Lewis acid and can react with nucleophiles. It is also a potent fumigant, effective against a wide range of insects and rodents, and has been used in pest control, particularly for stored products and in buildings. However, its use as a fumigant has been subject to scrutiny and regulation due to environmental and health concerns, including its potential as a greenhouse gas. Its toxicity necessitates careful handling and specialized application methods.
