The invention relates to new benzoylurea compounds having insecticidal and acaricidal activity, of the general formula
wherein
R, is a hydrogen atom or represents 1 or 2 halogen atoms;
Ar is a para-phenylene group or a para-pyridylene group, which groups may be substituted with 1 or 2 substituents selected from the group consisting of chlorine, methyl and trifluoromethyl;
B is an oxygen atom or represents a group having the formula
wherein R2 is a hydrogen atom or an alkyl group having 1-4 carbon atoms: and R is a cycloalkyl group, a cycloalkenyl group having 6-12 carbon atoms, which groups may be substituted with 1-3 substituents selected from the group consisting of alkyl and alkenyl having 1-6 carbon atoms, or wherein R is a bi- or polycyclic, saturated or unsaturated, hydrocarbyl group, having 8-14 carbon atoms and, if desired, substituted with 1-3 substituents selected from the group consisting of alkyl and alkenyl having 1-6 carbon atoms; with the proviso, that,
if Ar is a whether or not substituted paraphenylene group, and
R is a whether or not substituted cyclohexylgroup, or a saturated bi- or polycyclic hydrocarbyl group having 8-14 carbon atoms, then B does not represent an oxygen atom.
本发明涉及具有杀虫和杀螨活性的新苯甲酰脲化合物,其通式为
式中
R,是氢原子或代表 1 或 2 个卤素原子;
Ar 是对位亚苯基或对位亚吡啶基,这些基团可被 1 或 2 个从氯、甲基和三氟甲基组成的组中选出的取代基取代;
B 是氧原子或代表具有以下式子的基团
其中 R2 是氢原子或具有 1-4 个碳原子的烷基:R 是环烷基、具有 6-12 个碳原子的环烯基,这些基团可被 1-3 个从具有 1-6 个碳原子的烷基和烯基组成的组中选出的取代基取代,或者 R 是具有 8-14 个碳原子的双环或多环的、饱和或不饱和的烃基,如果需要,可被 1-3 个从具有 1-6 个碳原子的烷基和烯基组成的组中选出的取代基取代;但有一个限制条件,即
如果 Ar 是一个是否被取代的对苯基基团,且
R 是是否被取代的环己基,或具有 8-14 个碳原子的饱和双环或多环烃基;则 B 不代表氧原子。
