中文摘要：

以肼基取代嘧啶为起始原料，设计合成了16个新型的5-甲硫基-7-氯-1，2，4-三唑并[1，5-c]嘧啶-2-氧苄醚类及35个取代1，2，4-三唑并[1，5-c]嘧啶-2-氧苯醚类化合物，通过元素分析、MS和^1H NMR对所合成的化合物进行了结构表征．初步生测结果表明，部分化合物表现出不同程度的除草及杀菌活性．

英文摘要：

Sixteen novel 2-[substituted benzyloxy 7-chloro-5-methylsulfanyl-[1,2,4]-trlazolo[1,5-cJ pyrimidine derivatives and thirty-six novel substituted 2-phenoxy-[1,2,4]-triazolo[1,5-c]pyrimidine derivatives have been designed and synthesized using substituted 4-hydrazinopyrimidine as starting material. All synthesized compounds were confirmed by elemental analysis, MS and 1H NMR techniques. Preliminary bioassay indicates that some of them display good herbicidal and fungicidal activities.
