Dinitrogen trioxide structure

Nylon, nitrosated with dinitrogen trioxide according to Belg. Pat. 606 944 and stored cold, exploded on being allowed to warm to ambient temperature. The N-nitroso nylon would be similar in structure to iV-nitroso-iV-alkylamides, some of which are thermally unstable. Nylon components should therefore be excluded from contact with nitrosating agents. 

A kinetic study of structural effects on the A-nitrosation of amino acids by nitrite in aqueous solution has established that the dominant term in the rate equation corresponds to nitrosation by dinitrogen trioxide.189 Nitrosation by intramolecular migration of the nitroso group from an initially nitrosated carboxylate group can compete when the transition state has a five- or six-membered ring structure. Nitrosation of A-methyl-4-tolylsulfonylguanidine involves rapid nitrosation of the N-... 

The type and the stereochemistry of the products depends on the structure of the alkene and the experimental conditions. The use of oxygen as a carrier gas for dinitrogen tetroxide affects the course of the reaction in various ways, depending on the alkene, but it especially prevents reduction of dinitrogen tetroxide to dinitrogen trioxide and thereby permits a cleaner product mixture to be obtained, or it can divert the reaction course toward the formation of /(-nitro nitrates115. 

Dinitrogen trioxide, N2O3. Pure N2O3 cannot be isolated in the gaseous state since it exists in equilibrium with its dissociation products NO and NO2. However, its m.w. spectrum has been studied at -78°C and 0-1 mm pressure and indicates the planar structure shown. Some of the numerous suggestions as to the nature of the extraordinarily long N-N bond are discussed in ref. (9). The structure of crystalline N2O3 (at -115°C) proved too complex to analyse. ... 

Dinitrogen trioxide, N2O3 (nitrogen oxidation number +3), can be isolated only at low temperatures (r j -101 °C) as a blue solid and deep blue liquid, when stoichiometric amounts of NO and NO2 are combined. The molecule is planar (Structure 11.5 in Table 11.2). As the temperature is raised, the liquid becomes greenish as it disproportionates to NO and the brown NO2 ...
