摘 要:采用溴化法对环菌唑类杀菌剂丙环唑的合成进行了研究,总反应分三步进行。结果表明,第一步2,4-二氯苯乙酮的α单溴代反应较适宜的反应温度为5℃,较适宜的反应介质为四氯化碳,在此反应条件下,单溴代产物α-溴-2,4-二氯苯乙酮的收率为93%。丙环唑的总收率为69.5%(以2,4-二氯苯乙酮计),产品含量95.0%。产物结构经IR、1H NMR和MS表征。

Abstract:Propiconazole was synthesized by bromination,and its structure was determined by IR,1H NMR and MS. The results showed that the favorable temperature of α-monobromination of 2,4-dichloroacetophenone was 5℃,and the favorable reaction medium was carbon tetrachloride. At these conditions,the yields of monobromide reached 93%. The total yield of propiconazole was as high as 69.5%,and the product content was 95.0%.
Key words:propiconazole;α-bromo-2,4-dichloroacetophenone;2-(2,4-dichloro-phenyl)-2-bromomethyl-4-propyl-1,3-dioxolane;synthesis
