Chlorodifluoroamine is an inorganic chemical compound of nitrogen, chlorine, and fluorine with the molecular formula NClF₂. ^{[1] [2]}

Synthesis

The effect of fluorine on sodium azide in the presence of sodium chloride: ^[3]

2 F₂ + NaN₃ + NaCl → NClF₂ + 2 NaF + N₂

The effect of fluorine and chlorine on sodium azide:

3 F₂ + Cl₂ + 2 NaN₃ → 2 NClF₂ + 2 NaF + 2 N₂

Also, the reaction of ammonium chloride with fluorine:

NH₄Cl + 3 F₂ → NF₂Cl + 4 HF

Other methods are also known. ^[4]

Physical properties

The compound forms a colorlessб aie-stable gas ^[5] that decomposes when heated (sometimes with an explosion).

Chemical properties

The compound decomposes in several ways when heated:

2 NClF₂ → N₂F₂ + Cl₂

6 NClF₂ → 4 NF₃ + N₂ + 3 Cl₂
