APPLICATIONS

Nitroso is the prefix for NO- radical with trivalent nitrogen also known as hydroximino; oximido. Substances in which this group is attached to an oxygen atom are called nitrites (esters of nitrous acid); those in which the nitroso group is attached to a metal ion are called nitrosyls. Nitroso (-N=O) groups and azo (-N=N-) groups impart colour to the compound as these groups absorb light of characteristic wavelengths. Nitroso groups are strongly electron withdrawing and more similar to the C=O than the nirto group. Nitroso compound tends to dimerise. There is polarisation of the N=O bond and so behaves as a weak C=O. It undergoes addition of nucleophiles and condensation with primary amines and the anions of active methylene compounds. Nitroso groups are useful in addition and condensation reactions, stable nitroxide radical preparations, and isomerization to oxime. Oxidation undergoes readily with peracids, this is not available with nitro groups. Nitroso compounds are useful intermediates for the synthesis of target materials. Certain niroso derivatives are used as vulcanization accelerator by direct reacting with peroxy-free radical to tie up free radicals and adhesion promoter between metal and rubber. N-Nitrosodialkylamines which have N-nitroso functional group (–N–N=O) and amine functions (–NR2) are used as fire retardants in rubber & plastic formulations and as intermediaits for synthesis of catalyst, antioxidant, additive for lubricants, and softener of copolymers. N-Nitrosodimethylamine is also used in rocket fuels and as a solvent.
