Fourteen novel α-(substituted pyrazol-4-carbonyloxy)-α-arylmethyl phosphonates 7a～7n were synthesized from the intermediates 5-chloro-3-trifluoromethyl-1-phenylpyrazol-4-carbonyl chloride (4) and α-hydroxyl-α-arylmethyl phos- phonates (6). All compounds synthesized were identified by 1H NMR, IR spectra and elemental analysis, and the structure of 7j was further determined by X-ray single crystal diffraction method. The preliminary bioassay indicated that some compounds showed moderate fungicidal and herbicidal activities.

Key words: arylmethylphosphonate, synthesis, crystal structure, bioactivity
