Abstract

The autoxidation in alkaline media and in the dark of some 5-methyl substituted 3,4-dimethyl-3-pyrrolin-2-ones and 5-methylene substituted pyrrolidin-2-ones is studied. Both types of compounds are found to give autoxidation products that indicate very characteristic reaction pathways.

Zusammenfassung

Es wird die Autoxidation von einigen 5-methylsubstituierten 3,4-Dimethyl-3-pyrrolin-2-onen und 5-methylensubstituierten Pyrrolidin-2-onen in alkalischem Medium untersucht. Für beide Verbindungstypen wurden charakteristische Reaktionswege gefunden.
