    Abstract: Novel pyridyl derivatives are described, of the formula (I) in which Ar represents phenyl or pyridyl, each of which is optionally monosubstituted or polysubstituted by identical or different substituents, suitable substituents in each case being: halogen, cyano, nitro, in each case straight-chain or branched alkyl, alkoxy or alkylthio, each of which has 1 to 4 carbon atoms, in each case straight-chain or branched haloalkyl, haloalkoxy or haloalkylthio, each of which has 1 to 4 carbon atoms and 1 to 9 identical or different halogen atoms, in each case straight-chain or branched alkoxycarbonyl or alkoximinoalkyl, each of which has 1 to 4 carbon atoms in the individual alkyl moieties, and phenyl which is optionally monosubstituted or polysubstituted by identical or different substituents from the series comprising halogen and/or straight-chain or branched alkyl having 1 to 4 carbon atoms, and A represents a CH2 group or a radical of the formula with the exception of the compounds methyl 2-methoxy-1-{N-[6-(4-chlorophenylethynyl)2-pyridyl]-N-methyl}aminoacry late, methyl 2-methoxy-1-{N-[6-(2-fluoro-4-chlorophenylethynyl)-2-pyridyl]-N-methyl }aminoacrylate, methyl 2-methoxy-1-{N-(4-fluoro-2-chlorophenyl-ethynyl)-2-pyridyl]-N-methyl}a minoacrylate and the compounds methyl 2-methoxy-1-{N-(6-phenylethynyl)-2-pyridyl]-N-methyl}aminoacrylate, to their preparation, and to novel intermediates and end products of the formula (IV) and of the formula (IX) The novel pyridyl derivatives of the formulae (I), (IV) or (IX) are used as pesticides.
