Nitryl cyanide is an energetic chemical compound with the formula NCNO₂. Nitryl cyanide is a possible precursor to the theoretical

explosive An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An ex ...

Synthesis

Nitryl cyanide was first synthesized in 2014. The reaction of

nitronium tetrafluoroborate Nitronium tetrafluoroborate is an inorganic compound with formula NO2BF4. It is a salt of nitronium cation and tetrafluoroborate anion. It is a colorless crystalline solid, which reacts with water to form the corrosive acids HF and HNO3. As su ...
