翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク nitrilium ： ウィキペディア英語版 nitrilium A nitrilium ion is a nitrile that has been protonated, ()+, or alkylated, ()+.〔IUPAC Gold Book: (nitrilium ions )〕 ==Synthesis== Nitriles are only weakly basic and are poor nucleophiles, but they will attack very reactive electrophiles such as carbocations. Nitrilium salts can be prepared by reacting nitriles with trialkyloxonium salts. The nitrilium ions thus formed can then be reduced to secondary amines with sodium borohydride in diglyme. This is a convenient route to secondary amines of the form RCH2—NH—R′. 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「nitrilium」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.
