A series of 4-(substituted-3-phenylallylideneamino)-3-(3,4,5-trimethoxyphenyl)-1H-1,2,4-tria- zole-5(4H)-thione (3) were synthesized by condensation reaction of 4-amino-3-(3,4,5-trimethoxyphenyl)- 1H-1,2,4-triazole-5(4H)-thione (2) with various fluorocinnamaldehydes. Alkylation of 3 with alkyl halides affordedN-1,2,4-triazole moieties imines containing fluorocinnamylidene 4. Their structures were confirmed by 1H NMR, 13C NMR, IR and elemental analyses. The single crystal structure of compound 4g was determined by X-ray diffraction analysis, which revealed that the two double bonds N=C and C=Coutside the rings were of E,E-configurations. The preliminary bioassay showed that some of them exhibited moderate antiviral activity.
