Five novel N-(6-chloropyrid-3-yl)carbonyl-2-substituted arylsulfonamides 3a～3e were synthesized through the condensation of 6-chloropyrid-3-yl carboxylic acid (2) with 2-substituted arylsulfonamides (1) and characterized by elemental analyses, 1H NMR and IR spectra. The crystal structure of compound 3a was determined by X-ray diffraction analysis, which belongs to triclinic, space group . The preliminary bioassays showed that 3a～3d are of good plant-inhibiting activities and the activities to dicotyledon are superior to monocotyledon.

Key words: synthesis, crystal structure, herbicidal activity, arylsulfonamide
