本文综合论述研究分子立体异构农药的意义,分子构型与构效关系、研制高效立体农药的技术路线和异构体的分析鉴定。一、引言随着立体化学的发展,农药研究已深入到分子立体异构领域。研究发现:普通工厂生产的多虫畏、稳杀得、盖草能、禾草克、敌草胺等农药只有1/2是有效体。另一半是无效成分;通常生产的速灭杀丁、氯菊酯、苯醚菊酯等只 This article comprehensively expounds the significance, molecular structure and structure-activity relationship of molecular stereoisomeric pesticides, the technical route of developing efficient three-dimensional pesticides and the analysis and identification of isomers. I. INTRODUCTION With the development of stereochemistry, the research of pesticides has gone deep into the field of molecular stereoisomerization. The study found that: common factory production of insecticide, stable and stable, covered grass can, grass grams, rifampicin and other pesticides only 1/2 effective body. The other half is an invalid ingredient; the usual production speed kill Ding, permethrin, phenothrin and other only
