On September 30, 1993, Aadil, M.; Kirsch, G. published an article.Application of 2510-01-2 The title of the article was Synthesis of new 3-aminothieno- and -selenolo[2,3-b]pyridines. And the article contained the following:
Cyclization of alkylidenemalonitriles by the Vilsmeier-Haack reagent gives 2-chloro-3-cyanopyridines, e.g., I. These compounds are used as starting material for the synthesis of thieno[2,3-b]- and selenolo[2,3-b]pyridines, e.g., II (X = S, Se). The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Application of 2510-01-2
