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

of novel aryl pyrazole derivatives containing aminophosphonate were designed and synthesized on the basis of the commercial insecticide Fipronil. Their structures were confirmed by 1H NMR, FT-IR, elemental analysis, and compound 4 m was characterized by a single crystal X-ray diffraction analysis. The results of the preliminary bioassays showed that title compounds exhibited satisfactory insecticidal

derivatives containing aminomethanephosphonate and phenylfuran moieties were designed, synthesized and characterized by 1H NMR, 31P NMR and IR spectroscopy and elemental analyses. The single crystalstructure of diethyl [5-(4-chlorophenyl)furan-2-yl][3-cyano-1-(2,3,4-trifluorophenyl)-1H-pyrazol-5-ylamino]methanephosphonate (4l) was determined by X-ray diffraction. Preliminary bioassays showed that these
图形摘要 摘要 设计、合成了一系列含有氨基甲烷膦酸酯和苯基呋喃部分的新型芳基吡唑衍生物,并通过 1 H NMR、31 P NMR 和 IR 光谱以及元素分析对其进行了表征。[5-(4-氯苯基)呋喃-2-基][3-氰基-1-(2,3,4-三氟苯基)-1H-吡唑-5-基氨基]甲膦酸二乙酯(4l)的单晶结构为通过 X 射线衍射测定。初步生物测定表明,这些膦酸盐在 0.1% 时对库蚊和家蝇表现出令人满意的杀虫活性。特别是化合物4l表现出最有希望的KT50值,其优于Dextraltetramethrin®且与Prallehtrin®相似。还初步研究了构效关系。
