It is the anion of a nitronic acid, a tautomeric form of a nitro compound. Just as Ketones and Aldehydes exist in equilibrium with their enol tautomer in basic and acidic conditions, Nitro compounds exist in equilibrium under basic conditions with their nitronate tautomer. The base deprotonates the alpha-carbon, or the carbon directly attached to the nitrogen. The nitronate has two different resonance structures, one with a negative charge on the alpha carbon and a double bond between the nitrogen and one of the oxygens, and another resonance structure with a double bond between the nitrogen and the alpha carbon, and no double bond between the nitrogen and the oxygens. 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. == References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nitronate」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
