In order to find thiazolylacrylonitriles with good biological activities, eight 2-[4-(2,6-difluoro phenyl)thiazol-2-yl]-3-hydroxy-3-alkoxyl(aryloxy)acrylonitriles (5) and seven 2-[4-(2,6-difluorophenyl) thiazol-2-yl]-3-hydroxy-3-arylamineacrylonitriles (7), all of which were reported for the first time, were synthesized by the reaction of 2-[4-(2,6-difluorophenyl)thiazol-2-yl]acetonitrile (3) with substituted chloro-formates 4 and aryl isocyanates 6 in the presence of base. Their structures were confirmed by 1H NMR, IR, MS data and elemental analysis. The preliminary bioassay showed that all compounds had certain fungicidal and insecticidal activities. The inhibition rates of compounds 5f and 5h were above 95% against Colle-totrichum gossypii at 100 mg/L, and the mortality rates of compounds 5g and 7d were above 85% against Tetranychus urticae at 250 mg/L.

Key words: 2-[4-(2,6-difluorophenyl)thiazol-2-yl]acetonitrile, thiazolylacrylonitrile, synthesis, biological activity
