摘 要:采用溴化法對環(huán)菌唑類(lèi)殺菌劑丙環(huán)唑的合成進(jìn)行了研究,總反應分三步進(jìn)行。結果表明,第一步2,4-二氯苯乙酮的α單溴代反應較適宜的反應溫度為5℃,較適宜的反應介質(zhì)為四氯化碳,在此反應條件下,單溴代產(chǎn)物α-溴-2,4-二氯苯乙酮的收率為93%。丙環(huán)唑的總收率為69.5%(以2,4-二氯苯乙酮計),產(chǎn)品含量95.0%。產(chǎn)物結構經(jīng)IR、1H NMR和MS表征。 |
關(guān)鍵詞:丙環(huán)唑;α-溴-2,4-二氯苯乙酮;2-(2,4-二氯苯基)-2-溴甲基-4-丙基-1,3-二氧戊環(huán);合成 |

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 |
