Abstract:
    3-(Het)aryloxy(thio)carboxylic acid derivatives of the formula I where R1 is hydrogen, COOH or a radical which can be hydrolyzed to give COOH; R2 and R3 are each halogen, alkyl, haloalkyl, alkoxy, haloalkoxy or alkylthio; X is nitrogen or CR14, where R14 is hydrogen or, together with R3, forms a 3-membered or 4-membered alkylene or alkenylene chain, in each of which a methylene group is replaced by oxygen; R4 is alkyl, cycloalkyl, cycloalkenyl, alkenyl or alkynyl, each of which is unsubstituted or substituted; an unsubstituted or substituted five-membered or six-membered heteroaromatic structure containing one to three nitrogen atoms or one sulfur or oxygen atom; unsubstituted or substituted phenyl or naphthyl; R4 and R5, together with the neighboring carbon atom, form a 3-membered to 8-membered ring which may contain an oxygen or sulfur atom and which is unsubstituted or substituted; R5 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, haloalkyl, alkoxyalkyl, alkylthioalkyl or phenyl, each of which is unsubstituted or substituted; R6 is unsubstituted or substituted phenyl or naphthyl or an unsubstituted or substituted five-membered or six-membered heteroaromatic structure containing one to three nitrogen atoms or one sulfur or oxygen atom; Y is sulfur or oxygen or a single bond; and Z is sulfur or oxygen.
