【摘要】 从1-苯基-3-甲基-吡唑-5-酮出发,通过与Vismeier(DMF/POCl3)试剂反应得到1-苯基-3-甲基-5-氯-吡唑-4-甲醛(2),将其与羟胺肟化,再与相应的取代酰氯进行醇解反应,合成了17种未见报道的含氯羧酸吡唑醛肟酯类化合物,这些化合物的结构均经过1HNMR、IR、元素分析测试技术的证实,部分化合物还经过了EI-MS或LC/MS/MS测试技术的确证。初步生物活性测试结果证明,部分化合物具有较好的除草、杀菌、杀虫活性。更多还原

【Abstract】 Seventeen new carboxylic pyrazolyl oxime esters containing chlorine were prepared. Their （structures） were confirmed by virtue of ¹H NMR, IR and elemental analysis. Some of them were also confirmed by means of EI-Ms or LC/MS/MS. The preliminary bioassay for these compounds showed that some of them displayed good herbicidal and pesticidal as well as fungicidal activities.更多还原
