Nitryl cyanide is an energetic chemical compound with the formula NCNO
2. Nitryl cyanide is a possible precursor to
2,4,6-trinitro-1,3,5-triazine.
Synthesis
Nitryl cyanide was first synthesized in 2014. The reaction of
nitronium tetrafluoroborate with ''tert''-butyldimethylsilyl cyanide at −30 °C produces nitryl cyanide, with ''tert''-Butyldimethylsilyl fluoride and
boron trifluoride
Boron trifluoride is the inorganic compound with the formula BF3. This pungent, colourless, and toxic gas forms white fumes in moist air. It is a useful Lewis acid and a versatile building block for other boron compounds.

as byproducts.

The
conversion of this method is only 50%, and using an excess of ''tert''-butyldimethylsilyl causes the yield to drop even further.
