Nitrogen Oxide Fluorides

Oxyfluorides of nitrogen, i.e. compounds containing the grouping FNO, have been known for many years in the form of simple compounds, such as NOF and NO 2 F. Detailed studies of physical, structural, and chemical aspects of this class of compounds have been conducted only in recent years, after the potential of NF compounds as rocket propellants had been recognized. Several novel types of oxyfluorides of nitrogen, such as difluorohydroxyl amines, RONF 2 , or trifluoroamine oxide, F 3 NO, have been discovered recently. A further major development in ONF chemistry is indicated by the discovery that compounds of great chemical potential are formed between HF and NOF or NO 2 F, respectively. The compound O 2 NOF, although not an oxyfluoride of nitrogen, will also be discussed in this review, because of its particular chemical relationship to NO 2 F.
