A series of novel 5-arylmethoxy phenylpyrazole derivateves are prepared from 4-chloro-2- fluoro-5-methoxybenzaldehyde via a condensation, ring closure, methylation, etc. All these structures are identified by 1H NMR and HRMS techniques. Preliminary bioassay shows that some of the title compounds exhibit good herbicidal activity against the weeds. Especially, 4-cholro-3-[4-chloro-2-fluoro-5-(4-methoxy- benzy-loxy)phenyl]-1-methyl-5-trifluoromethyl)-1H-pyrazole shows 95% inhibition to abutilon at the dos-age of 9.375 g•hm-2.

Key words: herbicide, protoporphyrinogen oxidase inhibitor, pyrazole derivative
