摘　　要：以三氟乙酰乙酸乙酯、原甲酸三乙酯、甲基肼、苯基异硫氰酸酯等为原料,通过多步反应制备了一系列含吡唑的三唑硫醚类化合物,并考察了微波辐射对反应的影响.产物结构均经过1H NMR,13C NMR,HRMS和单晶衍射确证.对所有化合物进行了杀菌活性和除草活性进行测试,结果表明部分化合物对瓜类炭疽病具有一定的抑制效果,同时3-烯丙基硫基-5-(1-甲基-3-三氟甲基-1H-吡唑-4-基)-4-苯基-4H-1,2,4-三唑(6i)、2-氯-5-(((5-(1-甲基-3-三氟甲基-1H-吡唑-4-基)-4-苯基-4H-1,2,4-三唑-3-基)硫基)甲基)噻唑(6j)、4-(((5-(1-甲基-3-三氟甲基-1H-吡唑-4-基)-4-苯基-4H-1,2,4-三唑-3-基)硫基)甲基)苯腈(6m)表现出了对双子叶植物的除草活性.A series of novel 1,2,4-triazole derivatives were synthesized from ethyl trifluoroacetoacetate, triethyl orthoformate, methylhydrazine, phenyl isothiocyanate by multi-step reactions. Their structures were characterized by ~1H NMR, ^（13） C NMR, HRMS and X-ray diffraction. The target compounds were evaluated for their fungicidal activity and herbicidal activitiy. The results indicated that some of the title compounds displayed certain fungicidal activities against Colletotrichum orbiculare and herbicidal activity against dicotyledons.
