A series of new substituted benzaldehyde (or 2-furaldehyde) 3-(2-chloro-4-trifluoromethyl)phenoxy benzoylhy- drazones 4 have been designed and synthesized by the reactions of substituted aldehydes with intermediate 3 in 64%~89% yields. The structures of compounds 4 have been confirmed by 1H NMR, IR, EI-MS and elemental analyses. The structure of 4-chloro-benzaldehyde 3-(2-chloro-4-trifluoromethyl)phenoxy benzoylhydrazone (4f) has been determined by X-ray single crystal diffraction. The results of preliminary bioassay indicated that some compounds possess good fungicidal activities against Rhizoctonia solani and Botrytis cinereapers at a dosage of 50 mg/L and moderate herbicidal activity against the roots of rape and barnyard grass at 100 mg/L.

Key words: benzaldehyde, benzoylhydrazone, fungicidal activity, herbicidal activity
