Definition
ChEBI: 1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-5-[(2-methylprop-2-en-1-yl)amino]-4-[(trifluoromethyl)sulfinyl]-1H-pyrazole-3-carbonitrile is a member of the class of pyrazoles that is 1H-pyrazole that is substituted at positions 1, 3, 4, and 5 by 2,6-dichloro-4-(trifluoromethyl)phenyl, cyano, (trifluoromethyl)sulfinyl, and (2-methylprop-2-en-1-yl)nitrilo groups, respectively. It is a dichlorobenzene, a member of (trifluoromethyl)benzenes, a member of pyrazoles, a nitrile and a sulfoxide.
Production Methods
Flufiprole is produced through a multi step synthesis that builds its pyrazole core and fluoroaryl substituents. The process begins with preparation of a substituted pyrazole intermediate, typically via condensation of hydrazine derivatives with beta diketones. This core is then functionalised by introducing trifluoromethyl and fluoroaryl groups through halogenation and coupling reactions. Subsequent steps involve acylation to form the amide linkage and controlled fluorination to achieve the final flufiprole structure.
Mechanism of action
Targets the γ-aminobutyric acid-dependent neurotransmission system of insects
