A series of new substituted benzaldehyde (or 2-furaldehyde) 3-(2-chloro-4-trifluoromethyl)phenoxy benzoylhydrazones 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 1 H 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
