In addition to pyridines, α-chloroformylarylhydrazine hydrochloride 1 can also react with some N-heterocyclic compounds. The cycloaddition of 1 with isoquinoline was achieved to obtain 3. The production of 4, 5, 6 given by cycloaddition of 1 with pyridazine was de pendent on the reaction condition. Some heterocyclic compounds bearing an X-C=N (X:S, N) group on the ring can react with 1 to gain the
除了吡啶,α-氯甲酰芳基肼盐酸盐1也可以与一些N-杂环化合物反应。实现 1 与异喹啉的环加成得到 3。通过 1 与哒嗪的环加成反应生成 4、5、6 取决于反应条件。一些环上带有XC=N(X:S,N)基团的杂环化合物可以与1反应得到2,4-dihydro-1,2,4-triazol-3-one的衍生物。7、8、9 和 10 分别由 1 与 1,3,5-三嗪、1,4,5,6-四氢嘧啶、1,3-噻唑和 2-氨基-1,3-噻唑反应得到。2-氨基-1,3,4-噻二唑和3-氨基-1,2,4-三唑的反应得到相同的产物11。
