'''Carbonyl fluoride''' is a ] with the ] {{chem2|COF2|auto=1}}. It is a ]. This gas, like its analog ], is colourless and highly toxic. The molecule is ] with ''C''<sub>2v</sub> ], ]s of 1.174 Å (C=O) and 1.312 Å (C–F), and an F–C–F ] of 108.0°.<ref name="G&E">{{Greenwood&Earnshaw2nd|pages=304–305}}</ref> |

|
==Preparation and properties== |
|
|
Carbonyl fluoride is usually produced as a decomposition product of fluorinated hydrocarbons in the thermal decomposition thereof, for example from ] or ] in the presence of water: |
|
|
|
|
|
:{{chem2|CF4 + H2O → COF2 + 2 HF}} |
|
|
|
|
|
Carbonyl fluoride can also be prepared by reaction of phosgene with ] and the fluorination of ], although the latter tends to result in over-fluorination to ]. The fluorination of carbon monoxide with ] is convenient: |
|
|
|
|
|
:{{chem2|CO + 2 AgF2 → COF2 + 2 AgF}} |
|
|
|
|
|
Carbonyl fluoride is unstable in the presence of water, hydrolyzing to carbon dioxide and ]:<ref>{{ Cite book |author1=M. W. Farlow |author2=E. H. Man |author3=C. W.

==Safety== |
|
|
Carbonyl fluoride is very toxic with a ] of 2 ] as an 8-hour time weighted average and a 5 ppm as a short-term (15-minute average) exposure, where 1 ppm = 2.70 mg of carbonyl fluoride per 1 m<sup>3</sup> of air.<ref name=niosh>{{ cite web | url = https://www.cdc.gov/niosh/npg/npgd0108.html | publisher = CDC Centers for Disease Control and Prevention | work = NIOSH Pocket Guide to Chemical Hazards | title = Carbonyl Fluoride | access-date = 2013-09-10 }}</ref> |
