以3-(2-氯-4-三氟甲基苯氧基)苯甲酸为起始原料, 经氯化亚砜氯化后得中间体3-(2-氯-4-三氟甲基苯氧基)苯甲酰氯(1), 再与不同取代的苯酚反应, 合成了13个未见文献报道的3-(2-氯-4-三氟甲基苯氧基)苯甲酸酯(2). 通过1H NMR, IR, EI-MS和元素分析对所合成的化合物进行了结构表征, 3-甲基苯基3-(2-氯-4-三氟甲基苯氧)苯甲酸酯(2f)通过单晶X射线衍射进一步确证结构. 初步的除草活性测试结果表明: 大多数目标化合物在1.5 kg/ha剂量下对双子叶植物油菜和苋菜具有较高的抑制活性.

A series of new 3-(2-chloro-4-trifluoromethylphenoxy)benzoates (2) have been synthesized by the reactions of substituted phenols with intermediate 3-(2-chloro-4-trifluoromethylphenoxy)benzoyl chloride (1). The structures of compounds have been confirmed by 1H NMR, IR, EI-MS and elemental analyses. The structure of 3-methylphenyl 3-(2-chloro-4-trifluoromethylphenoxy)benzoate (2f) has been determined by single crystal X-ray diffraction. The results of preliminary bioassay indicated that most of title compounds possess a moderate herbicidal activity against dicotyledonous weeds.

Key words: synthesis, diphenyl ether, herbicidal activity
