英文摘要：

1,3,4-thiadiazole oxadiazole heterocyclic compounds play an important role in the research and development of medicines and pesticides because of their excellent insecticidal, weeding, anti plant virus, sterilization, antibacterial biological activities and the ad- vantages of high selectivity, high biological activity, low toxicity, and good environmental compatibility.In this paper, through thiadiazole diazotization by coupling reaction, three new series of compounds were synthesized and identified by means of I HNMR,IR and elemen- tary analysis. A preliminary study of their coordination reaction with the transition metal ions was carried out, to provide the experimental basis for their application in medicine.
