Other reactions with nitrogen oxides

With nitric oxide as oxidant, OH was the only detectable intermediate, and no NH was found in absorption. Further, whatever the mixture strength, only very small quantities of NO were observed in the burnt gas. 

More revealing in relation to the comparative lack of reactivity of nitric oxide are the observations of Wolfhard and Parker on H2 + NO2 flames. Here nitric oxide is found strongly in absorption in the burnt gas of both rich and lean flames, showing that it does not play a major part in the reaction. This conclusion is supported by measurement of the flame temperature of the stoichiometric mixture for H2 + 5NO2 = H2O + 5N2 [286]. Theoretically this should be 2890 K if the stoichiometry is as quoted. The measured flame temperature by line reversal was 1780 K. 

The reactions of hydrogen with nitrous and nitric oxides in closed vessels and in shock tubes will now be discussed.

Nitrogen oxides other than nitrogen dioxide have been studied for possible adverse health effects. Chemical analysis of ambient aerosols collected in southern California has revealed that nitrates exhibit particularly high values compared to other parts of the United States. These aerosols are generally acidic in nature and are composed of nitric acid and nitrate salts that are formed through photochemical reactions with nitrogen dioxide and other oxides of...

There are numerous investigations of the reactivity of di- and polyhalo-pyridazines, particularly polyfluoropyridazines. Aminolysis of l-phenyl-4,5-dichloropyridazin-6-one has been studied in detail. In this and other reactions with nucleophiles, the halogen atom at position 4 is substituted preferentially, although a mixture of 4-amino and 5-amino derivatives is formed in the reaction between 4,5-dihalopyridazin-6-ones and ammonia or amines. It has been now firmly established that displacement reactions on 3,6-dichloropyridazine 1-oxide with sulfur nucleophiles take place at position 6 in contrast to nitrogen or oxygen nucleophiles, where the 3-chlorine atom is replaced preferentially. In connection with the previously observed self-condensation of 3-chloro-6-methylpyridazine to a tricyclic product, the reaction between 3,6-dichloropyridazine and pyridine N-oxides was investigated. 3,6-Dichloropyridazine with 2-methylpyridine N-oxide at 100°-110°C affords three compounds (171, 172, and 173). With 2,6-dimethylpyridine N-oxide, an ether (174) is also formed. The isolation of... 

The initial intent to cover the subject exhaustively had to be abandoned because of the overwhelming amount of relevant literature. The following reactions are not covered but are briefly discussed, with references to reviews and seminal papers, in the section on Comparison with Other Methods reactions of carbanions and enolates and their surrogates with nitrogen oxides, nitrite and nitrate esters, and nitroso and nitro compounds reactions of enolates with diazonium salts, including the Japp-Klingemann reaction the diazo transfer reaction except as it interferes with the synthesis of azides the animation of boranes and the Neber rearrangement.
