International Classification:

A01N 4340
C07D40100

US Classification:

504253

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; 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; Z is cyano; and 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.

Abstract:

The invention describes novel 1-arylimidazoles 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; Y is hydrogen, halogen, alkyl, alkoxy, alkoxyalkylideneimino, alkylsulfenyl, alkylsulfinyl or alkylsulfonyl; Z is hydrogen, halogen, alkyl, preferably methyl; and R. sub. 2, R. sub. 3, R. sub. 4, R. sub. 5 and R. sub. 6 are individually hydrogen, halogen or an unsubstituted or halo-substituted alkyl, alkoxy, alkylsulfenyl, alkylsulfinyl or alkylsulfonyl. The invention further describes intermediates and processes to make the compounds, compositions of the compounds, and methods of use of the compounds for the control of arthropods (especially mites, aphids or insects), nematodes, helminths, or protozoa.
