Abstract
Oxonitrile in der Heterocyclensynthese: Einige neue Synthesemethoden für Pyridazin‐, Pyrazol‐, Pyridin‐ und Pyrido[2,3‐d]pyridazin‐Derivateω‐Cyanacetophenon geht in Anwesenheit von katalytischen Mengen von Cyanacetamid Knoevenagel‐Selbstkondensation ein und ergibt in der Schmelze das neue Oxonitril 2. Dieses reagiert mit Benzoldiazonium‐chlorid. Hydrazinen und CH‐aciden Verbindungen zu heterocyclischen Ringsystemen.Keywords
