翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク enol ether ： ウィキペディア英語版 enol ether An enol ether is an alkene with an alkoxy substituent. The general structure is $R\_1R\_2C=CR\_3-O-R\_4$ with R an alkyl or an aryl group. Enol ethers and enamines are so-called activated alkenes or electron rich alkenes because the oxygen atom donates electrons to the double bond by forming a resonance structure with the corresponding oxonium ion. This property makes them reactive substrates in certain organic reactions such as the Diels-Alder reaction. An enol ether can be considered the ether of the corresponding enolate, hence the name. Two simple enol ethers are methyl vinyl ether and 2,3-dihydrofuran. ==See also== *Silyl enol ether 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「enol ether」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.
