Abstract:

Seventeen new sulfonylurea derivatives with trifloromethyl group in the pyrimidine ring were designed and synthesized, based on NK92825 and NK94827. Their structures were confirmed by 1H NMR and elemental analysis. Preliminary herbicidal activities of these new sulfonylurea compounds were determined by pot bioassay experiments at dosage of 375 g/ha. The results show that some derivatives display good heribicidal activities.

Key words: Sulfonylurea; Trifloromethyl-pyrimidine; Herbicidal activity
