It contains a double bonded oxygen atom and an alkyl group. In organic chemistry, the acyl group (IUPAC name: alkanoyl) is usually derived from a carboxylic acid . Therefore, it has the formula RCO-, where R represents an alkyl group that is attached to the CO group with a single bond. Although the term is almost always applied to organic compounds, acyl groups can in principle be derived from other types of acids such as sulfonic acids, phosphonic acids. In the most common arrangement, acyl groups are attached to a larger molecular fragment, in which case the carbon and oxygen atoms are linked by a double bond. ==Acyl compounds== Well-known acyl compounds are the acyl chlorides, such as acetyl chloride (CH3COCl) and benzoyl chloride (C6H5COCl). These compounds, which are treated as sources of acylium cations, are good reagents for attaching acyl groups to various substrates. Amides (''RC(O)''NR2) and esters (''RC(O)''OR’) are classes of acyl compounds, as are ketones (''RC(O)''R) and aldehydes (''RC(O)''H). 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「Acyl」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.
