Nitronate
General chemical structure of a nitronate
A nitronate (IUPAC: azinate) in organic chemistry is a functional group with the general structure R1R2C=NO2−.[1] It is the anion of a nitronic acid, a tautomeric form of a nitro compound. A nitronic acid is also called an aci form. In the Nef reaction nitronic acids are degraded to ketones. They can be alkylated on oxygen and used as a dipole in 1,3-dipolar cycloadditions.
