翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hydrogen atom abstraction ： ウィキペディア英語版 Hydrogen atom abstraction Hydrogen atom abstraction or hydrogen atom transfer (HAT) in chemistry is any chemical reaction in which a hydrogen free radical is abstracted from a substrate according to the general equation: X. + H-Y -> X-H + Y. Examples of HAT reactions are oxidative reactions in general, hydrocarbon combustion and reactions involving cytochrome P450 containing an iron(V)-oxo unit. The abstractor is usually a radical species itself. An example of an closed-shell abstractor is chromyl chloride. HAT can take place through proton-coupled electron transfer.〔Lai, W., Li, C., Chen, H. and Shaik, S. (2012), ''Hydrogen-Abstraction Reactivity Patterns from A to Y: The Valence Bond Way''. Angew. Chem. Int. Ed., 51: 5556–5578. 〕 ==Non-radical Hydrogen Abstraction== It is reported in literature that during the synthesis of a Coelenterazine derivative, a non-radical hydrogen abstraction was observed on a substituted aminoimidazole in a typical Sandmayer hyroxilation condition. 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「Hydrogen atom abstraction」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.
