Silver nitrite is an inorganic compound with the formula AgNO2.[2]
Applications
Silver nitrite has many applications. Notable examples include:
- The production of aniline compounds.
- General oxidizing agent.
- Victor Meyer type nucleophilic substitution reactions with organobromides or organoiodides forming nitro compounds.[3]
- Nitroalkene synthesis with nitryl iodide generated in-situ from silver nitrite and elemental iodine.[4]
Production
Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite.[3] Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite:
- AgNO3 (aq) + NaNO2 (s) → NaNO3 (aq) + AgNO2 (precipitate)
Alternatively, it can be produced by the reaction between silver sulfate and barium nitrite.
