8 novel Schiff bases of 5-substituted sulfonamide were synthesized as the intermediates under mild conditions using microwave irradiation or ultrasonic irradiation, and then 16 novel benzenesulfonylurea compounds modified at the 5-position of the benzene ring were synthesized. The structures of all sulfonylurea compounds were confirmed by elemental analysis, MS and 1H NMR techniques. Herbicidal activity of these new sulfonylurea compounds was determined by rape disc and pot bioassay experiments. The result indicated that their herbicidal activity against broadleaf weeds was better than monocotyledonous weeds.

Key words: Schiff base, sulfonylurea, synthesis, herbicidal activity
