翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Thiocarboxylic acid ： ウィキペディア英語版 Thiocarboxylic acid Thiocarboxylic acids are organosulfur compounds related to carboxylic acids by replacement of one oxygen centre by sulfur. There are two possible tautomers, RC(S)OH and RC(O)SH, which are sometimes written as 'carbothioic O-acids' and 'carbothioic S-acids' respectively. The carbothioic S-acid tautomer RC(O)SH is far more common. In the laboratory, the most common thiocarboxylic acid is thioacetic acid. A naturally occurring thiocarboxylic acid is 2,6-pyridinedicarbothioic acid, which functions as a siderophore. Thiocarboxylic acids are more acidic than the corresponding carboxylic acids. Thiocarboxylic acids are typically prepared from the acid chloride: :C6H5C(O)Cl + KSH → C6H5C(O)SH + KCl ==Dithiocarboxylic acids== Dithiocarboxylic acids, with the formula RCS2H, are also known. They are less common than the monothio derivatives. Such compounds are commonly prepared by the reaction of carbon disulfide with a Grignard reagent: :RMgX + CS2 → RCS2MgX :RCS2MgX + HCl → RCS2H + MgXCl 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「Thiocarboxylic acid」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.
