This colourless liquid is a strong base with a higher pKa than typical amines. It was originally prepared from tetramethylthiourea via ''S''-methylation and amination, but alternative methods start from cyanogen iodide. ==Uses== TMG is mainly used as a strong, non-nucleophilic base for alkylations, often as a substitute for the more expensive bases DBU and DBN.〔 Since it is highly water-soluble, it is easily removed from mixtures in organic solvents. It is also used as a base-catalyst in the production of polyurethane. 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「1,1,3,3-Tetramethylguanidine」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.
