1-Benzoyl-3-substituted ureas of the formula
wherein each R is independently selected from the group consisting of H, Br, Cl, F, CH3 or OCH3, with the proviso that R cannot simultaneously represent more than one hydrogen atom, and with the further proviso that when one R moiety represents hydrogen the other R moiety cannot simultaneously represent OCH3; X = 0 or S; and R1 is independently selected from the group consisting of a substituted 3-isoxazolyl, a substituted 5-isoxazolyl and a substituted 3-benzisoxazolyl, have been found useful as insecticides. The compounds are prepared by reacting the appropriate ben- zovl isocvanate or benzoyl isothiocyanate of the formula
with an amine of formula NH2R1
式中的 1-苯甲酰基-3-取代脲
其中每个 R 独立地选自由 H、Br、Cl、F、CH3 或 OCH3 组成的组,但 R 不能同时代表一个以上的氢原子,而且当一个 R 代表氢时,另一个 R 不能同时代表 OCH3;X = 0 或 S;R1 独立地选自由取代的 3-异恶唑基、取代的 5-异恶唑基和取代的 3-苯并异恶唑基组成的组。这些化合物的制备方法是将适当的异钒酸苯甲酰酯或异硫氰酸苯甲酰酯与式 NH
与式 NH2R1 的胺反应制得。
