The invention relates to new barbituric acid derivatives of the general formula
wherein
Ris a substituted or unsubstituted phenyl group or heteroaryl group having 5 or 6 ring atoms, the heteroaryl group comprising one or more hetero atoms selected from the group consisting of N, O and S, and the substituents being selected from the group consisting of halogen, cyano, nitro, formyl, acetyl, C₁-C₄ alkyl, C₁-C₄ haloalkyl, C₁-C₄ alkoxy, C₁-C₄ haloalkoxy and optionally substituted phenoxy;
R₁is a C₃-C₅ alkyl group, a C₃-C₅ alkenyl group, a C₃-C₅ alkynyl group, a cyclopropyl group or a cyclopropyl(C₁-C₄)alkyl group, and
R₂is a C₁-C₄ alkyl group or an amino group;
as well as salts and metal complexes of the said compounds.
These compounds may be used in compositions for the control of insects, in particular aphids, in agriculture, horticulture and silviculture.
本发明涉及通式如下的新巴比妥酸衍生物
式中
Ris 一个取代或未取代的苯基或具有 5 或 6 个环原子的杂芳基,杂芳基包括一个或多个杂原子,这些杂原子选自由 N、O 和 S 组成的组、取代基选自由卤素、氰基、硝基、甲酰基、乙酰基、C₁-C₄ 烷基、C₁-C₄ 卤代烷基、C₁-C₄ 烷氧基、C₁-C₄ 卤代烷氧基和任选取代的苯氧基组成的组;
R₁ 是 C₃-C₅ 烷基、C₃-C₅ 烯基、C₃-C₅ 炔基、环丙基或环丙基(C₁-C₄)烷基,以及
