地昔尼尔合成工艺的改进

摘要

Dicyclanil is a new insecticide with strong market demand. The process in this article improve the synthetic method, use cheap and low risk reagents, simplify the post-processing method. After condensation, cyclization, amination, oxidation and ammoniation five steps to get dicyclanil, the total yield is more than 40%, purity over 99% and the product structure is confirmed by1HNMR.%地昔尼尔是一种新型杀虫剂，现有地昔尼尔制备工艺复杂，反应条件苛刻，生产成本过高。通过改进其合成方法，使用易得、低毒试剂，简化了后处理方法，经缩合、环合、胺化、氧化和氨化五步反应得到本品，产品结构经1HNMR确认，总收率达到40%以上，产品纯度99%以上。
