Nitrogen-oxygen compounds nitro

Catalytic cleavage of the nitrogen-oxygen bond occurs very frequently as in reduction of nitro compounds, oximes, and various heterocyclics these reactions are discussed in separate chapters. Considered here are N-oxides, hydroxylamincs, and N- and C-nitroso compounds. 

Nitrobenzenes with an ortho or a para hydroxyl or amino function form an exceptional group of compounds in which the nitro function can readily be reduced to amino in alkaline solution. Heterolytic cleavage of the nitrogen-oxygen bond in the phenylliydroxylamine intermediate is promoted by any 2- or 4-substituent which can donate a lone pair of electrons. Further reduction steps then lead to the overall... 

Effect of the Atmosphere. The composition of radiolysis products depends substantially on the degree of saturation of the irradiated system with oxygen. In a nitrogen atmosphere, the major radiolysis products of the system TBP-diluent-HN03 were alkyl-nitro and -nitrate compounds. However, in the presence of oxygen, the yields of these compounds were sharply reduced, and an accumulation of carbonyl compounds was measured (11, 25). 

One synthetic approach is to synthesize nitrogen-rich compounds (N > 60 %), which also contain oxidizing groups (e.g. nitro — N02, nitrimino =N -N02, Fig. 9.6), in order to achieve the best possible oxygen balance (Q). This is important because in principal, it is always better to have the oxidizer and fuel combined in one molecule (in contrast to mixtures), because this generally results in superior... 

Here again a double bond has been broken this time a nitrogen/oxygen bond, and a new carbon/nitrogen double bond has been formed in its place. This is called the nitro/aci tautomerism, and again each tautomer may be isolated, because each tautomer represents a real compound and not just a hypothetical model. These tautomers are shown below. 

Mixed Oxygen and Nitrogen derivatives compounds of the amide type, and then nitroso- and nitro- derivatives.
