Description

A six-membered aromatic ring-substituted benzoyl or thiobenzoyltrifluoroethylamine compound and its application Technical Field

[0001] This invention belongs to the field of agricultural insecticides and acaricides. Specifically, it relates to a six-membered aromatic ring-substituted benzoyl or thiobenzoyltrifluoroethylamine compound or its agriculturally acceptable salt and its application. Background Technology

[0002] Because pests and mites develop resistance to insecticides and acaricides after a period of use, it is necessary to continuously develop new compounds and compositions with insecticidal and acaricidal activity. At the same time, with the increasing demand for agricultural and livestock products and the growing emphasis on environmental protection, there is a ongoing need for new, more cost-effective, and environmentally friendly insecticides and acaricides.

[0003] Patents CN1878466A and WO2006118155 disclose biphenyl amide derivatives with agricultural bactericidal and fungicidal effects, as shown in general formulas A and B, respectively, but do not describe their agricultural insecticidal or acaricidal effects. Patent CN101678007A describes a six-membered aromatic ring-substituted benzoyl derivative as shown in general formula C, but the amine moiety of the amide bond in the described compounds is limited to alkylamines, anilines, or heteroarylamines. Patent WO2024192147 describes a benzene ring-substituted benzoyl derivative with herbicidal activity, as shown in general formula D, but the amine moiety of the amide bond in the described compounds is limited to sulfonamides.

[0004] Patent WO2020036134 discloses triazole-substituted benzamide derivatives and patent JP2021121582A discloses pyrazole-substituted benzamide derivatives, which have insecticidal and acaricidal effects, but the insecticidal and acaricidal activities of these disclosed compounds are not satisfactory.

[0005] In the prior art, no reports have been made of the six-membered aromatic ring-substituted benzoyl or thiobenzoyltrifluoroethylamine compounds of general formula I of this invention, or their agriculturally acceptable salts, and their acaricidal and insecticidal activities. Compared with the prior art, the compounds of this invention have higher insecticidal and acaricidal activities. Summary of the Invention

[0006] The purpose of this invention is to provide a novel six-membered aromatic ring-substituted benzoyl or thiobenzoyl trifluoroethylamine compound or its agriculturally acceptable salt, which can be used in agriculture and horticulture, as well as in domestic or disease prevention applications for livestock and pets, as an insecticide, acaricide, nematicide, etc.
