Zusammenfassung

o-Acetoxyphenyl-acetoxyimino-glyoxal-phenylhydrazone gehen bei der Verseifung mit Na2CO3 in Derivate des 2H-1,2,3-Triazols über. Unter dem Einfluß von stärkerem Alkali (20proz. NaOH) lagern sich diese Triazole zu Triazolo-benzisoxazolen um.

Abstract

Hydrolysis of o-acetoxyphenyl-acetoximino-glyoxal-phenylhydrazones with Na2CO3 leads to derivatives of 2H-1,2,3-triazoles. Using strong alkalies (20% NaOH) the triazoles rearrange to triazolo-benzisoxazoles.
