NOF is a highly reactive [[halogenation|fluorinating agent]] that converts many metals to their fluorides: :''n''NOF + [[metal|M]] → [[fluoride|MF<sub>''n''</sub>]] + [[hydrogen fluoride|HF]] NOF also fluorinates [[fluoride]]s to form [[adduct]]s that have a [[salt]]-like character, such as [[nitrosyl fluoroborate|NOBF<sub>4</sub>]]. Aqueous solutions of NOF 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]]: :NOF + [[water (molecule)|H<sub>2</sub>O]] → [[nitrous acid|HNO<sub>2</sub>]] + HF :3HNO<sub>2</sub> → [[nitric acid|HNO<sub>3</sub>]] + [[nitric oxide|2NO]] + H<sub>2</sub>O Nitrosyl fluoride can also convert [[alcohol]]s to [[Nitrite#Organic nitrites|nitrites]]: :[[alcohol|ROH]] + NOF → [[Nitrite#Organic nitrites|RONO]] + HF ==Uses== Nitrosyl fluoride is used as a [[solvent]]{{Fact|date=March 2007}} and as a [[fluorinating]] agent.{{Fact|date=March 2007}} ==References== {{Greenwood&Earnshaw}} ==External links== * [http://webbook.nist.gov/cgi/cbook.cgi?ID=C7789255 WebBook page for NOF] * [http://www.npi.gov.au/database/substance-info/profiles/44.html National Pollutant Inventory - Fluoride and compounds fact sheet] [[Category:Fluorides]] [[Category:Nitrosyl compounds]] [[Category:Acyl halides]] {{inorganic-compound-stub}}
