Abstract
The invention describes novel 1-(2-pyridyl)pyrazoles of formula (I) ##STR1## wherein typically preferred substituents are: X is S(O).sub.n R.sub.1, in which R.sub.1 is an alkyl group, preferably a methyl group, which is fully substituted by halogen atoms, and n is 0, 1 and 2; PA0 Y is hydrogen, halogen, cyano, alkylsulfenyl, alkylsulfinyl, alkylsulfonyl, alkoxy, amino, alkylamino, dialkylamino, trialkylammonium salt, cyanoalkylamino, alkoxyalkylamino, alkoxycarbonylamino, alkylcarbonylamino, haloalkylcarbonylamino, alkylaminocarbonylamino, dialkylaminocarbonylamino or alkoxyalkylideneimino, wherein the alkyl and alkoxy moieties are a linear or branched chain, containing one to four carbon atoms, and the halo-substitution consists of one or more halogen atoms, which are the same or different, up to full substitution of the alkyl moiety; PA0 Z is cyano; and PA0 R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are individually hydrogen, halogen or an unsubstituted or halo-substituted alkyl or alkoxy, cyano or nitro; with the proviso that at least one of R.sub.2 to R.sub.5 is other than hydrogen. The invention further describes intermediates and processes to make the compounds, compositions of t…
