芳基吡唑亚胺类衍生物研究进展
摘 要
文章从农药的历史,目前所使用的高效农药的类型合成工艺为分类,目前农药中使用比较广泛的四种类型农药:芳基吡唑类、新烟碱类、菊酯类和磺酰脲类,从优点、市场前景和劣势分析,作者以最为典型的芳基吡唑类农药氟虫腈为例,列举了3种不同的合成方法,从能否适应工业生产来分析工艺,最后介绍了亚胺类化合物的目前3种常用的合成工艺,胺与羰基化合物的缩合、胺和醇的氧化缩合以及二级胺的氧化。对未来农药发展方向做了简要分析。

Abstract
Article content from history pesticides currently used pesticides and efficient synthesis of type classification, the four types of pesticides which used frequently: Arylpyrazoles, neonicotinoids, pyrethroids and sulfonylurea, analysis from the advantages and disadvantages of the market prospects. The author of the most typical arylpyrazoles pesticides fipronil. Lists three different synthesis methods, from industrial production to analyze the suitability. Finally, the current three kinds of commonly used synthetic process imine compounds: Condensation of an amine with a carbonyl compound, Condensation of the amine oxide and an alcohol and oxidation of secondary amines. The author analyzes the future direction of pesticides in the end.
Key words: Pesticides; Aryl pyrazole; Imine
1.1农药的历史
人类在长期的农业生产实践中,积累和发展了使用化学药品与农作物病、虫、草、鼠害作斗争的丰富经验。我们现在称这些化学药品为农药。
农药的发展大体经历了3个历史阶段:天然药物时代、无机合成农药时代和有机合成农药时代。
