Abstract1-Arylpyrazol-5-ones added to the C≡N bond of benzoylcyanamide in the presence of Ni(OAc)2, giving the corresponding pyrazol-5-one diaminomethylidene derivatives, which were used as reagents for the synthesis of heterocyclic compounds and as chelating ligands.
摘要 1-Arylpyrazol-5-ones 在 Ni(OAc)2 存在下加到苯甲酰氰胺的 C≡N 键上,得到相应的 pyrazol-5-one 二氨基亚甲基衍生物,用作合成杂环化合物的试剂和作为螯合配体。
