Patent ID: 7767625

Claim:
A compound of the formula I in which R 1 is a C 1 -C 4 alkyl, C 2 -C 4 alkenyl or C 2 -C 4 alkynyl group; or R 1 is a C 1 -C 4 alkyl, C 2 -C 4 alkenyl or C 2 -C 4 alkynyl group which is mono- or polysubstituted by halogen, hydroxy, cyano, C 1 -C 4 alkoxycarbonyl, formyl, nitro, C 1 -C 4 alkoxy, C 1 -C 4 haloalkoxy, C 1 -C 4 alkylthio, C 1 -C 4 haloalkylthio, HC(OR 4 )═N— and/or R 5 R 6 NN═C(H)—; R 4 , R 5 and R 6 independently of one another are hydrogen or C 1 -C 4 alkyl; R 2 is a C 1 -C 6 alkyl group; or R 2 is a C 1 -C 6 alkyl group which is mono- or polysubstituted by halogen, hydroxy, cyano, C 1 -C 4 alkoxycarbonyl, formyl, nitro, C 1 -C 4 alkoxy, C 1 -C 4 haloalkoxy, C 1 -C 4 alkylthio, C 1 -C 4 haloalkylthio, HC(OR 7 )═N— or R 8 R 9 NN═C(H)—; R 7 , R 8 and R 9 independently of one another are hydrogen or C 1 -C 4 alkyl; R 3 is hydrogen or halogen; and A is A 1 in which R 11 , R 12 and R 13 independently of one another are selected from hydrogen, halo, cyano, nitro, C 1 -C 4 alkyl, C 1 -C 4 haloalkyl, C 1 -C 4 alkoxy- C 1 -C 4 alkyl and C 1 -C 4 haloalkoxy-C 1 -C 4 alkyl, provided that at least one of R 11 , R 12 and R 13 is not hydrogen; or a tautomer or an enantiomer of these compounds.
