It is far less reactive than the other nitrogen trihalides nitrogen trichloride, nitrogen tribromide, and nitrogen triiodide, all of which are explosive. Alone among the nitrogen trihalides it has a negative enthalpy of formation. It is prepared in modern times both by direct reaction of ammonia and fluorine and by a variation of Ruff's method. [6]

Tetrafluorohydrazine was originally prepared from nitrogen trifluoride using a copper as a fluorine atom acceptor: [3] 2NF 3 + Cu → N 2 F 4 + CuF 2. A number of F-atom acceptors can be used, including carbon, other metals, and nitric oxide. These reactions exploit the relatively weak N-F bond in NF 3. [4]
Nitrogen fluorides are compounds of chemical elements nitrogen and fluorine. Many different nitrogen fluorides are known: Nitrogen monofluoride, NF; Nitrogen difluoride radical, ·NF 2; Nitrogen trifluoride, NF 3; Nitrogen pentafluoride, NF 5; Dinitrogen difluoride, N 2 F 2; Tetrafluorohydrazine, N 2 F 4; Fluorine azide, N 3 F ...
Atmospheric concentration of SF 6, NF 3, and several widely used HFCs and PFCs between years 1978 and 2015 (right graph).Note the logarithmic scale. The most common F-gases are hydrofluorocarbons (HFCs), which contain hydrogen, fluorine, and carbon.
The reaction of nitrogen trifluoride with fluorine and boron trifluoride at 800 °C yields the tetrafluoroborate salt: [6] NF 3 + F 2 + BF 3 → NF 4 BF 4. NF + 4 salts can also be prepared by fluorination of NF 3 with krypton difluoride (KrF 2) and fluorides of the form MF n, where M is Sb, Nb, Pt, Ti, or B. For example, reaction of NF 3 with ...
Trifluoramine oxide was first discovered in 1966 independently by two different groups. One way to produce it was by an electric discharge in a mixture of oxygen on nitrogen trifluoride. Another even less yielding method is by reacting noble metal fluorides (IrF 6 or PtF 6) with nitric oxide. [1]
Many metals form trifluorides, such as iron, the rare-earth elements, and the metals in the groups 3, 13 and 15 of the periodic table. Most metal trifluorides are poorly soluble in water except ferric fluoride and indium(III) fluoride , but several are soluble in other solvents.
