In order to find novel pesticide from pyrazole compounds, a series of new pyrazole derivatives carrying trifluoromethyl benzoyl oxime ester moiety were prepared. The structures of all the title compounds were determined by 1H NMR, 13C NMR, MS and elemental analysis. Preliminary bioassay displayed that most of the target compounds showed certain insecticidal activities at the concentration of 500 μg/mL. When the concentration was reduced to 200 μg/mL, compounds 5b, 5c, 5d, 5i, 5l and 5n were still active against Aphis craccivora with inhibitory values of 90%, 90%, 80%, 80%, 80% and 80%, respectively.

Key words: trifluoromethyl benzoyl, pyrazole, synthesis, biological activity
