It can be produced from furfural by the catalytic action of cyanide ions.〔 Denis Lorient (1999), ''(New ingredients in food processing: biochemistry and agriculture ).'' Woodhead Publishing. ISBN 1-85573-443-5. 366 pages 〕 ==Reactions== Furoin synthesis from furfural is also catalyzed by vitamin B1 (thiamine). In 1957, R. Breslow proposed that this reaction involves a relatively stable carbene form of thiamine:〔 〕〔 〕 In the catalytic cycle shown below two molecules of furfural react to give furoin, via a thiazol-2-ylidene catalyst, resulting from loss of one proton at carbon 2 of the thiazolium cation of vitamin B1: This was the first evidence for the existence of persistent carbenes. 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「Furoin」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.
