以2,3-二氯吡啶和水合肼为起始原料,经取代、缩合、氧化、醚化、成环和开环等多步反应合成一系列结构新颖的含多氟烷基吡唑环的邻甲酰氨基苯甲酰胺类化合物,结构经1H NMR和HRMS确证,并测试了目标化合物的杀虫活性.杀虫活性结果表明,在浓度0.8 mg/L下,大部分化合物对粘虫(Mythimna separata Walker)具有100%杀虫活性;在浓度2 mg/L下,N-(4-氯-2-(异丙基氨基甲酰)-6-甲基苯基)-1-(3-氯吡啶-2-基)-3-((1-甲基-3-五氟乙基-4-三氟甲基-1H-吡唑-5-基)氧基)-1H-吡唑-5-酰胺(8c)和N-(4-氯-2-(环丙基氨基甲酰)-6-甲基苯基)-1-(3-氯吡啶-2-基)-3-((1-甲基-3-五氟乙基-4-三氟甲基-1H-吡唑-5-基)氧基)-1H-吡唑-5-酰胺(8d)对斜纹夜蛾(Prodenia litura Fabricius)杀虫活性大于60%;在浓度0.08 mg/L下,N-(4-氯-2-(二甲基氨基甲酰)-6-甲基苯基)-1-(3-氯吡啶-2-基)-3-((1-甲基-3-五氟乙基-4-三氟甲基-1H-吡唑-5-基)氧基)-1H-吡唑-5-酰胺(8l)对小菜蛾(Plutella xylostella Linnaeus)杀虫活性达到82.5%.

A series of novel anthranilic diamides containing polyfluoroalkyl pyrazole were synthesized using 2,3-dichloropyridine and hydrazine hydrate as starting materials via substitution, condensation, oxidation, etherification, cyclization and ring cleavage reaction. The title products were characterized by 1H NMR and HRMS. The bioassay results indicated that most of title compounds exhibited 100% insecticidal activitiy against Mythimna separata Walker at 0.8 mg/L, N-(4-chloro-2-(isopropylcarbamoyl)-6-methylphenyl)-1-(3-chloropyridin-2-yl)-3-((1-methyl-3-(perfluoroethyl)-4-(trifluoromethyl)-1H-pyrazol-5-yl)oxy)-1H-pyrazole-5-carboxamide (8c) and N-(4-chloro-2-(cyclopropylcarbamoyl)-6-methylphenyl)-1-(3-chloropyridin-2-yl)-3-((1-methyl-3-(perfluoroethyl)-4-(trifluoromethyl)-1H-pyrazol-5-yl)oxy)-1H-pyrazole-5-carboxamide (8d) showed more than 60% larvicidal activity against Prodenia litura Fabricius at 2 mg/L, and the mortality of N-(4-chloro-2-(dimethylcarbamoyl)-6-methylphenyl)-1-(3-chloropyridin-2-yl)-3-((1-methyl-3-(perfluoroethyl)-4-(trifluoromethyl)-1Hpyrazol-5-yl)oxy)-1H-pyrazole-5-carboxamide (8l) against Plutella xylostella Linnaeus reached 82.5% at 0.08 mg/L.
