Cyanogen fluoride (molecular formula: FCN ; IUPAC name: carbononitridic fluoride ) is an inorganic linear compound which consists of a fluorine in a single bond with carbon , and a nitrogen in a triple bond with carbon. It is a toxic and explosive gas at room temperature. It is used in organic synthesis and can be produced by pyrolysis of cyanuric fluoride or by fluorination of cyanogen .

24-409: A 24 cm separation between the two branches. A triplet band is observed at around 451 cm . Cyanogen fluoride reacts with benzene in the presence of aluminum chloride to form benzonitrile in 20% conversion. It also reacts with olefins to yield an alpha,beta-fluoronitriles. FCN also adds to olefins which have internal double bonds in the presence of strong acid catalyst. FCN can be stored in

48-508: A molecular mass of 45.015 gmol . Cyanogen fluoride has a boiling point of –46.2 °C and a melting point of –82 °C. The stretching constant for the CN bond was 17.5 mdyn/A and for the CF bond it was 8.07 mdyn/A, but this can vary depending on the interaction constant. At room temperature, the condensed phase converts rapidly to polymeric materials. Liquid FCN explodes at –41 °C when initiated by
60-467: A squib. The fluorine NMR pattern for FCN showed that there was a triplet peak centered at 80 ppm (3180 cps) with a 32-34 cps splitting between adjacent peaks because of the N nucleus. This splitting is absent near freezing point and it collapses to a singlet peak. The IR spectrum of FCN shows two doublet bands at around 2290 cm (for the C ≡ N) and 1078 cm (for the C-F). The C-F doublet band has
72-426: A stainless steel cylinders for over a year when the temperature is -78.5 °C (solid carbon dioxide temperature). Cyanogen fluoride undergoes violent reaction when in the presence of boron trifluoride or hydrogen fluoride. Pure gaseous FCN at atmospheric pressure and room temperature does not ignite by a spark or hot wire. FCN air mixtures however are more susceptible to ignition and explosion than pure FCN. FCN
84-433: Is by the fluorination of cyanogen. Nitrogen trifluoride can fluoridate cyanogen to cyanogen fluoride when both the reactants are injected downstream into the nitrogen arc plasma. With carbonyl fluoride and carbon tetrafluoride, FCN was obtained by passing these fluorides through the arc flame and injecting the cyanogen downstream into the arc plasma. Cyanogen fluoride (FCN) is a toxic, colorless gas. The linear molecule has
96-409: Is pyrolyzed (becoming a pyrolysate) at a rate of 50g/hr, and appears as fluffy white solid collected in liquid nitrogen traps. These liquid nitrogen traps are filled to atmospheric pressure with nitrogen or helium. This process yields crude cyanogen fluoride, which is then distilled in a glass column at atmospheric pressure to give pure cyanogen fluoride. Another method of synthesizing cyanogen fluoride
108-437: Is synthesized by the pyrolysis of cyanuric fluoride (C 3 N 3 F 3 ) at 1300 °C and 50mm pressure; this process gives a maximum of 50% yield. Other products observed were cyanogen and CF 3 CN. For pyrolysis, an induction heated carbon tube with an internal diameter of 0.75 inches is packed with 4 to 8 mesh carbon granules and is surrounded by graphite powder insulation and a water-jacketed shell. The cyanuric fluoride
120-419: Is useful in synthesis of important compounds such as dyes, fluorescent brighteners and photographic sensitizers. It is also very useful as a fluorinating and nitrilating agent. Beta-fluoronitriles, which are produced when FCN is reacted with olefins, are useful intermediates for preparing polymers, beta-fluorocarboxylic acids and other fluorine containing products. Useful amines can be obtained. Cyanogen fluoride
