    Description / Table of Contents: The Beckmann Reaction of Phenyl-substituted 1,3-DioximesThe 1,3-diketones 1a - c react with hydroxylammonium chloride to give isoxazolin-5-ols 2a - c predominantly, in addition to dioximes 3a and b, respectively. The anti (E,E) configuration of the dioximes was established by UV and 1H NMR. By Beckmann reaction of 3a, b and d, 4H-pyrazole N-oxides 4a, b and d were formed. The amphi (Z,E) configuration of 1,3-bis(hydroxyimino)-1,3-diphenyl-2-propanone (6) was established by 13C NMR.
    Notes: Aus den 1,3-Diketonen 1a - c werden mit Hydroxylammoniumchlorid überwiegend Isoxazolin-5-ole 2a - c neben den Dioximen 3a und b gebildet. Die anti (E,E)-Konfiguration dieser Dioxime wurde aus den UV- und 1H-NMR-Spektren bestimmt. Die Beckmann-Reaktion von 3a, b und d führt zu 4H-Pyrazol-N-oxiden 4a, b und d. 1,3-Bis(hydroxyimino)-1,3-diphenyl-2-propanon (6) hat amphi (Z,E)-Konfiguration, wie das 13C-NMR-Spektrum zeigt; 6 fragmentiert bei der Beckmann-Reaktion.
