翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Self-condensation ： ウィキペディア英語版 Self-condensation Self-condensation is an organic reaction in which a chemical compound containing a carbonyl group acts both as the electrophile and the nucleophile in an aldol condensation. It is also called a symmetrical aldol condensation as opposed to a mixed aldol condensation in which the electrophile and nucleophile are different species. For example, two molecules of acetone condense to a single compound mesityl oxide in the presence of an ion exchange resin:〔Ketone Condensations Using Sulfonic Acid Ion Exchange Resin N. Lorette; ''J. Org. Chem.''; 1957; 22(3); 346-347.〕 :2 CH3COCH3 → (CH3)2C=CH(CO)CH3 + H2O For synthetic uses, this is generally an undesirable, but spontaneous and favored side-reaction of mixed aldol condensation, and special precautions are needed to prevent it. == 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「Self-condensation」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.
