General description
Sodium nitrite (NaNO2) is an inorganic compound that is commonly used as a reagent and catalyst in synthetic organic chemistry.
Application
Co-catalyst for catalytic oxidation of alcohols under aerobic, solvent-free conditions.
Solvent free aerobic oxidation of alcohols with 1-methyl-2-azaadamantane N-oxyl as a recyclable catalyst through phase separation
Solvent free aerobic oxidation of alcohols with 1-methyl-2-azaadamantane N-oxyl as a recyclable catalyst through phase separation
Sodium nitrite can be used as a reagent in:
It can also be used as a nitrating agent in organic synthesis. For example, NaNO2 is used in direct C-H nitration, ipso-nitration, and nitration via transition metal-catalyzed cross-coupling reaction.
- The Sandmeyer reaction for converting amines into diazo derivatives, and nitration reaction.
- The oxidative C-C bond formation reaction in the presence of oxygen as the terminal oxidant.
- The oxidative carbonitration of alkenes in the presence of K2S2O8.
It can also be used as a nitrating agent in organic synthesis. For example, NaNO2 is used in direct C-H nitration, ipso-nitration, and nitration via transition metal-catalyzed cross-coupling reaction.

A cyclic voltammetric method is described for the determination of nitrite by using a multiwalled carbon nanotube paste electrode (MWCNT) that was modified with chitosan-functionalized silver nanoparticles (Chit-AgNPs). The AgNPs were prepared by one step procedure using chitosan as stabilizing

An automated turbidimetric system using multiwelled plates was used to examine the effects of different combinations of NaCl (0.5-8.0% w/v), NaNO2 (0-400 micrograms/ml) pH (4.6-7.4) and temperature (5-30 degrees C) on the growth of Listeria monocytogenes in tryptone soya broth.
