Description

N-苯基吡唑衍生物杀虫剂
技术领域 本发明涉及吡唑类农药杀虫剂。
背景技术 1989年法国罗纳 -普朗克公司开发了吡唑类广谱杀虫剂, 其商品名为 "Regent", 该化合物是一种对许多害虫具有优异防效的广谱杀 虫剂, 例如: 对半翅目、 鳞翅目、 缨翅目、 鞘翅目等害虫以及对环戊二烯 类、 菊酯类、 氨基甲酸酯类杀虫剂已产生抗药性的害虫, 都显示出了极高 的敏感性。 商品名为 "Regent"的分子结构式为:
Figure imgf000002_0001
1999年罗纳公司申请专利 US 5,916,618还介绍了一系列 Regent衍生物 的合成, 主要在杂环上的氨基取代为乙酰氨基、 氯乙酰氨基。 三氟甲基亚 磺酰基衍生为三氟甲基磺酰基、 三氟甲硫基等化合物。
2000年, 法国罗纳公司申请的美国 US 6,015,910中有如下飄勺化
Figure imgf000002_0002
该化合物的某些特点超过了 " Regent"。 对棉蚜内吸活性 LC5() = 0.21ppm,而 Regent为 11.3ppm;对高梁蚜内吸活性 LC5o=0.6ppm,而 Regent >20ppm。
目前, 越来越严格的环境要求, 使我国老农药品种, 特别是一些不适 应环境及对人畜安全有毒的农药品种 (例如: 高毒有机磷农药) 难免被淘 汰, 就必须开发具有活性高、 环境相容性好、 作用方式新颖的农药新品种, 来提高我国农药工业的发展水平及农作物的化学防治水平, 解决农药品种 的更新换代, 降低对环境的压力。
