翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク orthoester ： ウィキペディア英語版 orthoester In organic chemistry, an orthoester is a functional group containing three alkoxy groups attached to one carbon atom, i.e. with the general formula RC(OR’)3. Orthoesters may be considered as products of exhaustive alkylation of unstable orthocarboxylic acids and it is from these that the name 'ortho ester' is derived. An example is ethyl orthoacetate, CH3C(OCH2CH3)3, more correctly known as 1,1,1-triethoxyethane. Orthoesters are used in organic synthesis as protecting groups for esters. == Synthesis == Orthoesters can be prepared by the Pinner reaction, in which nitriles react with alcohols under acid catalysis: :RCN + 3 R’OH → RC(OR’)3 + NH3 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「orthoester」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.
