On October 31, 1980, Taylor, Edward C.; Sun, Jung Hui published an article.Quality Control of 2-Aminomalononitrile 4-methylbenzenesulfonate The title of the article was A new synthesis of aminomalononitrile tosylate. And the article contained the following:
The title salt (I) was prepared from NaCH(CN)2. Thus, 2,4,6-Me3C6H2SO2ONH2 was added to NaCH(CN)2 in THF, the mixture stirred under N2 2.5 h at 0°, the 2,4,6-Me3C6H2SO3Na formed was separated, 4-MeC6H4SO3H added, and the mixture refrigerated overnight to give I. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Quality Control of 2-Aminomalononitrile 4-methylbenzenesulfonate
The Article related to aminomalononitrile tosylate, malononitrile amino tosylate, Aliphatic Compounds: Nitriles, Isonitriles, and Acyl Cyanides and other aspects.Quality Control of 2-Aminomalononitrile 4-methylbenzenesulfonate
