【摘要】 环戊口恶草酮是一种新型口恶唑啉二酮类除草剂,N-(2-氟-4-氯-5-环戊氧基苯基)氨基甲酸乙酯是合成该除草剂的重要中间体之一。本文以5-硝基-2-氯-4-氟苯酚为原料,经催化加氢还原、烷基化反应等合成了N-(2-氟-4-氯-5-环戊氧基苯基)氨基甲酸乙酯。该方法操作简便,四步总收率达56.7%。更多还原

【Abstract】 Pentoxazone is a novel oxazolidinedione herbicide.Ethyl N-(4-chloro-5-cyclopentyloxy-2-fluorophenyl) carbamate is an important intermediate of pentoxazone.It is synthesized of the catalytic hydrogenation,alkylation with 5-nitro-2-chloro-4-fluorophenol as raw material.The method has the advantage of simplicity,and the total yield is 56.7%.更多还原
