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]

Nitrogen trifluoride can fluoridate cyanogen to cyanogen fluoride when both the reactants are injected downstream into the nitrogen arc plasma. [3] 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.
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:GHS templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:GHS templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last ...
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]
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.

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 ...
