A urea derivative of the general formula,
(wherein X is a halogen), which has higher insecticidal activity than known similar compounds with lowered toxicity to mammals and fishes. The derivative can be produced by reacting 2-fluoro-4-halo- aniline with 2,6-difluorobenzoyl isocyanate or reacting 2-fluoro-4-halo-phenylisocyanate with 2,6-difluorobenzamide.
一种通式为
(其中 X 为卤素)的脲衍生物,其杀虫活性高于已知的类似化合物,对哺乳动物和鱼类的毒性较低。该衍生物可通过 2-氟-4-卤代苯胺与 2,6-二氟苯甲酰异氰酸酯反应或 2-氟-4-卤代苯基异氰酸酯与 2,6-二氟苯甲酰胺反应制得。
