A series of novel 1,2,4-triazole derivatives were synthesized from ethyl trifluoroacetoacetate,triethyl orthoformate,methylhydrazine,phenyl isothiocyanate by multi-step reactions.Their structures were characterized by 1H NMR,13C NMR,HRMS and X-ray diffraction.The target compounds were evaluated for their fungicidal activity and herbicidal activitiy.The results indicated that some of the title compounds displayed certain fungicidal activities against Colletotrichum orbiculare and herbicidal activity against dicotyledons.
Key words： pyrazole; 1,2,4-triazole; synthesis; fungicidal activity; herbicidal activity
