Nitryl fluoride, addition

Smardzewski has produced several reports of work on nitrogen hypo-fluorite, NOF.118-120 Simultaneous deposition of F2 and NO in Ar and N2 matrices at 8 K produces species that give three new i.r. absorptions in addition to the normal F—N-bonded FNO. Isotope studies help to assign these bands to the isomer NOF, which appears to be a bent molecule, undergoing photorearrangement to the more stable FNO on exposure to radiation below 280 nm. Similarly, the isomer of nitryl fluoride ONOF has been detected at low temperatures.120121... 

Nitryl chloride (NO2CI) also adds to alkenes, to give p-halo nitro compounds, but this is a free-radical process. The NO2 goes to the less-substituted carbon. Nitryl chloride also adds to triple bonds to give the expected l-nitro-2-chloro alkenes. The compound FNO2 can be added to alkenes by treatment with HF in HNOa or by addition of the alkene to a solution of nitronium tetrafluoroborate (NOJBF4, see 11-2) in 70% polyhydrogen fluoride-pyridine solution (see also 15-37).
