Physical Data
: bp −28.5 °C (at 743 torr) estimated.
Solubility
: soluble in THF, chloroform, and most organic solvents.
Form Supplied in
: solution in THF (0.5 M).
Preparative Methods
: azidotrifluoromethane
1,2
was prepared by the reaction of trifluoronitrosomethane with hydrazine, followed by the treatment with chlorine gas (eq 1).
3–5
Azidotrifluoromethane was also prepared starting from electrophilic azide reagent tosyl azide and TMSCF
3
activated with cesium fluoride and was isolated by distillation (eq 2).

is thermally relatively stable and safe to use in laboratory in solution at temperatures <150 °C.
6
Can be stored in THF solution in a fridge or a freezer due to compound volatility. Storage in pure form in a stainless‐steel cylinder at ambient temperature at several atmospheres' pressure did not result in any significant decomposition.
5
Decomposition was reported at 1120 K to give N

and FCN.

Also, an explosion was reported at 330 °C.
