TLDR
In this paper, the Einwirkung von Schwefel auf vinyloge methylenaktive Nitrile, gestattet auch die Einbeziehung von Alkylarylketonen in die Reaktion.Abstract:
Aliphatische Ketone, Aldehyde sowie β-Dicarbonylverbindungen reagieren mit methylenaktiven Nitrilen und Schwefel in Gegenwart von Aminen bei Raumtemperatur zu 2-Aminothiophenen. — Eine Variante der Synthese, die Einwirkung von Schwefel auf vinyloge methylenaktive Nitrile, gestattet auch die Einbeziehung von Alkylarylketonen in die Reaktion.read more
