Abstract

Highly substituted chalcones 1 do not react with two molecules of hydroxylamine affording dioximes 2 or hydroxyamino-oximes 3 as expected according to von Auwers' procedure1): only one molecule of hydroxylamine is consumed leading to trans-configurated 2-benzoyl-3-phenyl-1H-aziridines 4. Aus den hochsubstituierten Chalkonen 1 entstehen nicht die nach von Auwers1) zu erwartenden Dioxime 2 oder ...
