Nitrosonium nitrate, NONO3-, is formed upon the oxidation of nitric oxide in certain hydrocarbon solutions at cryogenic temperatures. The infrared spectrum of this compound was studied at temperatures ranging from 79 to 205K. Low-temperature 77 - 90K oxidative nitration of isobutylene and subsequent oxidation of the unstable product with N2O4 at 273K yield 2-nitratoisobutyraldehyde and 2-nitratoisobutyric anhydride. Nitrosonium nitrate may be transitory intermediate in the reaction of N2O4 with olefins at about 273K. Tetrafluorohydrazine was found to react with a number of inorganic and organometalloid compounds. Most of these reactions occur only above 243K. This suggests that the difluoramino radical, present in equilibrium with tetrafluorohydrazine in this temperature range, is the reactive species.
