Twenty eight aryl pyrazole derivatives containing 5-fluorouracil were designed and synthesised via the key intermediate 1-aryl-3-methyl-1 H-pyrazole-5-carboxylic acid. The structures of target compounds were confirmed by 1H NMR, FT-IR, EA and their insecticidal activities were evaluated. The bioassays revealed that aryl pyrazole derivatives containing 5-fluorouracil exhibited excellent insecticidal activities against Culex pipiens and Musca domestica at a concentration of 0.1%. Some compounds still showed good insecticidal activities even at a concentration of 0.05%.
通过关键中间体 1-芳基-3-甲基-1 H-吡唑-5-羧酸,设计并合成了含有 5-氟尿嘧啶的 28 种芳基吡唑衍生物。通过 1H NMR、FT-IR 和 EA 确认了目标化合物的结构,并评估了它们的杀虫活性。生物测定结果表明,含有 5-氟尿嘧啶的芳基吡唑衍生物在 0.1% 的浓度下对喙库蚊和家蝇具有极佳的杀虫活性。一些化合物即使在 0.05% 的浓度下仍表现出良好的杀虫活性。
