The present invention relates to a process for the regioselective synthesis of 1-alkyl-3-halo-alkylpyrazole-4-carboxylic acid derivatives by cyclization of 2,3-disubstituted acrylic acid derivatives, and to the hydrazones formed as intermediates in the process.
Disclosed are compounds of Formula 1, including all stereoisomers, N-oxides, and salts thereof,
wherein
E, X, G, W
2
and Z are as defined in the disclosure.
Also disclosed are compositions containing the compounds of Formula 1 and methods for controlling plant disease caused by a fungal pathogen comprising applying an effective amount of a compound or a composition of the invention.
Also disclosed are compounds of Formula 1A including all stereoisomers, N-oxides, and salts thereof,
wherein
E, X, G and Z
1
are as defined in the disclosure.
Also disclosed is the use of the compounds of Formula 1A as intermediates for preparing compounds of Formula 1.
