'''氟磺酸氟'''，化学式 FSO<sub>3</sub>F，形式上是[[氟]]的[[氟磺酸盐]]，但其中的氟并不是以阳离子形式存在的。

== 制备 ==
氟磺酸氟可以由[[三氧化硫]]和[[氟气]]在 200&nbsp;°C 下反应而成。<ref name="Dictionary of Inorganic Compounds" />

<chem>SO3 + F2 -> FOSO2F</chem>

== 性质==
氟磺酸氟是一种强[[氧化剂]]，可能爆炸。<ref name="Dictionary of Inorganic Compounds" />

它和[[碱]]反应，产生[[氟磺酸盐]]、[[氟化物]]、[[水]]和[[氧气]]。<ref name="Fluorine Fluorosulfonate">{{cite book|author=Frank B. Dudley, George H. Cady, David F. Eggers Jr.|title=Fluorine Fluorosulfonate|publisher=J. Am. Chem. Soc.|date=1956-01|pages=290-292|DOI=10.1021/ja01583a011}}</ref>

<chem>FSO3F + 2 OH- -> SO3F- + F- + H2O + 1/2O2</chem>
