Nitryl Cyanide, NCNO₂

Abstract

The elusive nitryl cyanide, NCNO2, has been synthesized and characterized. It was prepared in good yield, isolated by fractional condensation, characterized by NMR and vibrational spectroscopy, and studied by theoretical calculations. Nitryl cyanide holds promise as a high energy density material (HEDM) and might also prove useful as a HEDM building block. The simplicity and inherent stability of nitryl cyanide, together with the known multitude of nitriles in interstellar space, suggest that the compound might also be a potential candidate for observations in atmospheric and interstellar chemistry.

Synthesis and Characterization of Fluorodinitroamine, FN(NO2)2

“…To circumvent this separation problem, the possibility of using different solvents was investigated. As in the case of the recently discovered NCNO 2 , [15] compatibility, solubility, volatility and liquid-range problems render this a very difficult task. For example, the use of CH 3 CN suffers from its higher melting point of À41 8C and in some cases the formation of CH 3 COF.…”
