This indirect method is often used because aryl halides are relatively weaker nucleophiles than aliphatic halocarbons and thus poorly alkylate diethyl malonate. Methods using Caesium carbonate and copper(I) iodide have been developed to overcome this difficulty however. 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「Diethyl phenylmalonate」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.
