-
Ten novel diheterocyclic thio-ether compounds containing 1,2,4-triazolo[1,5-a] pyrimidine and 1,2,4-triazole moieties were designed and synthesized with 2-mercapto-5,7-dimethyl-[1,2,4]triazolo[I,5-a] pyrimidine as starting material.All the compounds obtained were comfired by MS and 1H NMR.Preliminary biological activity test indicates most of compounds 6 display good activity against C.beticola.Especially,compounds 6b,6e,6f,6g and 6h can reach grade A(≥90%) at a concentration of 50 μg/L.
