翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク benzyl ： ウィキペディア英語版 benzyl In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure C6H5CH2-. Benzyl features a benzene ring attached to a CH2 group.〔Carey, F. A., and Sundberg, R. J.; ''Advanced Organic Chemistry, Part A: Structure and Mechanisms'', 5th ed.; Springer: New York, NY, 2008. pp 806–808, 312–313.〕 ==Nomenclature== In IUPAC nomenclature the prefix benzyl refers to a C6H5CH2 substituent, for example benzyl chloride or benzyl benzoate. Benzyl is not to be confused with phenyl with the formula C6H5. The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example the molecule, is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C6H5CH2. The benzyl carbocation has the formula C6H5CH2+; the carbanion has the formula C6H5CH2−. None of these species can be formed in significant amounts under normal conditions, but they are useful referents for discussion of reaction mechanisms. 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「benzyl」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.
