the commercial insecticide Fipronil, a series of novel arylpyrazole derivatives containing the cyhalothroyl thiourea moiety were designed and synthesized via the key intermediate 5-amino-3-cyano-1-(substituted phenyl) pyrazole. The structures of target compounds were characterized by 1H NMR, FT-IR, elemental analysis and single crystal X-ray diffraction analysis. Their insecticidal activities against
图形摘要 摘要 在商用杀虫剂氟虫腈的基础上,通过关键中间体 5-氨基-3-氰基-1-(取代苯基)吡唑,设计并合成了一系列含有三氟甲酰硫脲部分的新型芳基吡唑衍生物。目标化合物的结构经1H NMR、FT-IR、元素分析和单晶X射线衍射分析表征。评价了它们对淡色库蚊和家蝇的杀虫活性。生物测定结果表明标题化合物表现出令人满意的杀虫活性。其中,化合物 7t ((E)-3-(2-chloro-3, 3, 3-trifluoroprop-1-en-1-yl)-N-((3-cyano-1-(2, 6-dichloro-3, 3, 3-trifluoroprop-1-en-1-yl)-N-((3-cyano-1-(2, 6-dichloro- -4-(三氟甲基)苯基)-1H-吡唑-5-基)氨基甲硫酰基)-2,2-二甲基环丙烷甲酰胺)由于其最低的 KT50 值而表现出最好的杀虫活性,这优于商业杀虫剂右旋四氯菊
