It is widely used in the laboratory synthesis of organic compounds. == Reactions == Apart from acting as the synthetic equivalent of an ethyl anion synthon for nucleophilic addition, ethylmagnesium bromide may be used as a strong base to deprotonate various substrates such as alkynes: :RC≡CH + EtMgBr → RC≡CMgBr + EtH In this application, ethylmagnesium bromide has been supplanted by the wide availability of organolithium reagents. 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「ethylmagnesium bromide」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.
