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 d...
