Abstract:
    The invention discloses 3-Halo-3-hetarylcarboxylic acid derivatives having the formula I in which R is a formyl group, a group CO2H or a radical which can be hydrolyzed to COOH, and the remaining substituents have the following meanings: R2 and R3 are halogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy or C1-C4-alkylthio; X is nitrogen or CR13, where R13 is hydrogen or together with R3 forms an alkylene or alkenylene chain in which in each case one methylene group is replaced by oxygen; R4 is an unsubstituted or substituted five- or six-membered heteroaromatic ring which contains one to three nitrogen atoms and/or one sulfur or oxygen atom; R5 is hydrogen, substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl or phenyl; Y is sulfur, oxygen or a single bond; and Z is halogen.
