Abstract：
Seven Schiff bases have been prepared by an acid catalyzed condensation of 5-alkyl-4-amino- 2,4-dihydro-1,2,4-triazole-3-thione with substituted aromatic aldehydes, the structures of which have been confirmed by 1H NMR, IR spectra and elemental analysis. Their biological activities to several vegetable pathogens have been tested, showing that they exhibited good fungicidal activities. |
