Fluorinated pyrethroid compound and application thereof

Abstract

The invention provides a fluorinated pyrethroid compound; and the chemical name of the compound is 2,5-dioxo-3-(2-propinyl) imidazolidinedione-1-methyl 2,2-dimethyl-3- (alkenyl) cyclopropane carboxylate, and the structural is as shown in the following formula (A), wherein X refers to a fluorine atom or one or more C1-C3 fluorinated alkyl halides replaced by the fluorine atoms. Compared with the prior art, the fluorinated pyrethroid compound has higher insecticidal activity. The invention also provides a preparation method and the application of the pyrethroid compound in preventing hygiene pests.

Description

technical field The invention relates to a pyrethroid compound, especially a pyrethroid compound containing halogenated hydrocarbons substituted by multiple fluorine atoms, and the application of the compound in killing sanitary pests. Background technique Japanese Patent Publication describes some pyrethroid compounds such as (4-allylphenyl)methyl(1RS)-trans-2,2-dimethyl-3-((E )-1-propenyl)cyclopropanecarboxylate and (2,3,5,6-tetrafluorophenyl)methyl(1R)-trans-2,2-dimethyl- 3-(2-Methyl-1-propenyl)cyclopropanecarboxylate. However, these compounds do not have sufficient insecticidal or acaricidal activity to be practical. It is known from the specification disclosed by EP-31199A that some fluorine-substituted benzyl esters of haloalkenyl cyclopropanecarboxylic acids have insecticidal activity, and in these compounds, the 1-position and 3 Isomers in which the substituents at the - position are in the cis configuration are more active than those in which the substituents at ...
