|Section2= |Section3= |Section7= |Section8= }} Carbonyl fluoride is the inorganic compound with the formula COF2. This gas, like its analog phosgene, is colourless and highly toxic. The molecule is planar with C2v symmetry. ==Preparation and properties== Carbonyl fluoride can be prepared by reaction of phosgene with hydrogen fluoride and the oxidation of carbon monoxide, although the latter tends to result in over-oxidation to carbon tetrafluoride. The oxidation of carbon monoxide with silver difluoride is convenient: :CO + 2 AgF2 → COF2 + 2 AgF Carbonyl fluoride is unstable in the presence of water, hydrolyzing to carbon dioxide and hydrogen fluoride.
