摘要

The cyclization of 2-dialkylamino-2u0002-halogeno- and 2-chloro-2u0002-(dialkylamino)acetanilides to quinoxaline derivativesnhas been studied in detail. These reactions proceed, respectively, through intramolecular aromatic nucleophilic ornaliphatic nucleophilic substitution reactions and depending on the substituents and the experimental conditions, theynlead to 3-oxoquinoxalinium salts or, after an alkyl chloride elimination, to quinoxalin-2-ones. Some new cases of thenlittle known intramolecular quaternization of tertiary amines with aryl halides are described.
