The present invention provides a fluorine-containing pyrazolecarbonitrile derivative and a method for producing the same, and a fluorine-containing pyrazolecarboxylic acid derivative obtained by using the fluorine-containing pyrazolecarbonitrile derivative and a method for producing the same.
A fluorine-containing acyacrylonitrile derivative prepared from a fluoroacyl derivative and an aminoacrylonitrile derivative, is reacted with a hydrazine derivative to produce a fluorine-containing pyrazolecarbonitrile derivative represented by Formula (1).
In Formula (1), Rf represents an alkyl group having 1 to 6 carbon atoms and substituted with at least one fluorine atom; R1 represents an alkyl group having 1 to 6 carbon atoms and R2 represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or the like.
The fluorine-containing pyrazolecarbonitrile derivative represented by Formula (1) is reacted with water to produce a fluorine-containing pyrazolecarboxylic acid derivative.

1-Alkyl-1H-pyrazole-4-carbaldehyde oximes reacted with acetic anhydride to give the corresponding nitriles, which is typical for anti isomers of aldoximes. The anti configuration of 5-methyl-1-propyl-1H-pyrazole-4-carbaldehyde oxime in crystal was unambiguously determined by X-ray analysis.
