Syntheses and biological activities of 1,2,4-triazolo-[3,4-b][1,3,4] thiadiazole dithiophosphates
Chen, Wen-Bin,Jin, Gui-Yu
, p. 543 - 549 (2004)
In this article, we incorporated the organic phosphorus group on to a triazolothiadiazole ring to prepare the title compounds fused 1,2,4-triazolo[3,4-b][1,3,4]thiadiazole heterocyclic compounds. From the results on biological activities, we found that mo
