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
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.
