Nitrosation

From Wikipedia, the free encyclopedia

Nitrosation is a process of converting organic compounds into nitroso derivatives, i.e. compounds containing the R-NO functionality.

[edit] C-Nitroso compounds

C-Nitroso compounds, such as nitrosobenzene, are typically prepared by oxidation of hydroxylamines:

RNHOH + [O] → RNO + H₂O

[edit] N-nitrosamines

N-nitrosamines, including the carcinogenic variety, arise from the reaction of nitrite sources with amino compounds. Typically this reaction proceeds via the attack of the nitrosonium electrophile on an amine:

NO₂^- + 2 H⁺ → NO⁺ + H₂O

R₂NH + NO⁺ → R₂N-NO + H⁺
