摘要: 通过二溴化物与唑酮1[R=(CH3)3C]或α-三唑基苯乙酮1(R=Ar)的亲核取代反应,合成了新型的环状三唑类化合物3和4,经元素分析,1HNMR,IR,EI-MS和X射线衍射等方法确证其结构,讨论了反应过程.生物活性测试发现大部分化合物具有很好的杀菌活性,尤其对小麦锈病具有较强的抑制作用.

关键词: 三唑, 二溴化物, 亲核取代反应, 生物活性

Abstract: The title compounds 3 and 4 were prepared by nucleophilic substitution reaction of compounds 1 with dibromide 2. Their structures were determined by elementary analysis, 1H NMR, IR, EI-MS and X-ray diffraction method. The reaction procedure was also studied in detail. From the screening results of biological activities, most compounds possess good fungicidal activities, especially against Puccinia recondita.

Key words: Triazole, Dibromide, Nucleophilic substitution reaction, Biological activities
