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
NH2OH·HCl 与 β-芳酰基丙烯酸的反应不明确:亲核试剂攻击羰基或 C=C 键。在后一种情况下,所得的 α-羟基-氨基衍生物转化为烯胺,可能通过脱水和异构化。将 1,2,4-三唑加成到 β-(对甲苯基)丙烯酸的 C=C 键上,然后用 60% NH2NH2·H2O 回流它们的加合物,得到二氢哒嗪酮衍生物。
