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-hydroxyl-amino 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. [ABSTRACT FROM AUTHOR] |
