Nitrosyl fluoride, FNO, is a covalently-bonded nitrosyl compound.
FNO is a highly reactive fluorinating agent that converts many metals to their fluorides:
FNO also fluorinates fluorides to form adducts that have a salt-like character, such as NOBF4.
Aqueous solutions of FNO are powerful solvents for metals, by a mechanism similar to that seen in aqua regia. Nitrosyl fluoride reacts with water to form nitrous acid, which then forms nitric acid:
Nitrosyl fluoride can also convert alcohols to nitrites:
[edit] Uses
Nitrosyl fluoride is used as a solvent[citation needed] and as a fluorinating agent.[citation needed]
