Disclosed are difluorobenzonitriles of the formula (I) in which Y is an alkyl, alkenyl, alkoxy, oxaalkyl or alkenyloxy with 1-12 C-atoms, one of the residues A?1 and A2¿ in the molecule is (a), in which X is CH or N, and the other residue A1 or A2 is selected from the following: (b) and (c), one of the residues Z?1 and Z2¿ is a single bond and the other residue Z1 or Z2 is -CH¿2?CH2- or a single bond and m is 0 or 1, with the provision that, if m = 1, Z?1 = Z2¿ = a single bond and one of the residues A?1 and A2¿ = pyrimidine-2,5-diyl and the other residue A1 or A2 = 1,4-phenylene, then A1 is pyrimidine-2,5-diyl. |
