Sulfuryl chloride fluoride is a chemical compound with the formula {{chem2|SO2ClF|auto=1}}. 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.{{cite journal |doi=10.1021/ic7010138|title=Syntheses, Solution Multi-NMR Characterization, and Reactivities of [C6F5Xe]+Salts of Weakly Coordinating Borate Anions, [BY4]-(Y = CF3, C6F5, CN, or OTeF5)|year =2007|last1=Koppe|first1 =Karsten|last2 =Bilir|first2 =Vural|last3=Frohn|first3=Hermann-J.|last4=Mercier|first4=Hélène P.

Preparation

The laboratory-scale synthesis begins with the preparation of potassium fluorosulfite:{{cite book | doi = 10.1002/9780470132401.ch29 | journal = Inorg. Synth. | author = Seel, F. | year = 1967 | volume = 9 | pages = 113–115 | last2 = Czerepinski | first2 = Ralph G. | last3 = Cady | first3 = George H. | title = Inorganic Syntheses | chapter = Potassium Fluorosulfite: (Potassium Fluorosulfinate) | isbn = 978-0-470-13240-1}}

:{{chem2|SO2 + KF → KSO2F}}

This salt is then chlorinated to give sulfuryl chloride fluoride{{cite book | doi = 10.1002/9780470132401.ch28 | journal = Inorg. Synth. | author = Seel, F. | volume = 9 | year = 1967 | pages = 111–113 | last2 = Duncan | first2 = Leonard C. | last3 = Czerepinski | first3 = Ralph G. | last4 = Cady | first4 = George H. | title = Inorganic Syntheses | chapter = Sulfuryl Chloride Fluoride and Sulfuryl Fluoride | isbn = 9780470132401}}

:{{chem2|KSO2F + Cl2 → SO2ClF + KCl}}

Further heating (180 °C) of potassium fluorosulfite with the sulfuryl chloride fluoride gives sulfuryl fluoride.

:{{chem2|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.{{cite journal | doi = 10.1016/S0022-1139(00)81102-1| title = A Convenient Preparation of Sulfuryl Chloride Fluoride| year = 1992| last1 = Prakash Reddy| first1 = V.| last2 = Bellew| first2 = Donald R.| last3 = Prakash| first3 = G.
