A urea derivative of the general formula, ##STR1## (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-haloaniline with 2,6-difluorobenzoyl isocyanate or reacting 2-fluoro-4-halo-phenylisocyanate with 2,6-difluorobenzamide.
一种尿素衍生物的一般公式为##STR1##(其中X是卤素),其具有比已知类似化合物更高的杀虫活性,对哺乳动物和鱼类的毒性降低。该衍生物可通过将2-氟-4-卤苯胺与2,6-二氟苯甲酰异氰酸酯反应或将2-氟-4-卤苯异氰酸酯与2,6-二氟苯甲酰胺反应来制备。
