In this article, we introduce organic phosphorus moiety into triazole ring to prepare O-dialkyl- dithiophosphoryl-S-acetoxy triazolo compounds and characterize their structures by elementary analysis and 1 HNMR and IR spectral data. From the results of biological activity screening, we found that the O-dialkyl-dithiophosphoryl-S-acetoxy triazolo compounds show lower fungicidal activities and their structures need to be optimized for the better.
