Reactions of NH2OH•HCl with β-aroylacrylic acids proceed ambiguously: a nucleophile
attacks either the carbonyl group or the C=C bond. In the latter case, the resulting α-hydroxylamino derivative converts into enamine, probably via dehydration followed by isomerization.
Addition of 1,2,4-triazole to the C=C bond of β-(p-toluyl)acrylic acid followed by refluxing of
their adduct with 60% NH2NH2•H2O gave a dihydropyridazinone derivative.
