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.
Sodium nitrite can be used as a reagent in:
- 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.
