Abstract:
A process for protecting warm-blooded animals from pests comprising the application of an effective pesticidal amount of a compound of formula (I) or one of its acid addition salts, whereinR is hydrogen, C1-C20-alkyl or â€”C(O)â€”R8; whereby R8 is C1-C20-alkyl, C1-C20-alkoxy, unsubstituted phenyl or phenyl which is substituted once or many times by C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, halogen, cyano, hydroxyl, alkoxy, amino or nitro; R1 is hydrogen, C1-C20-alkyl, â€”C(O)â€”R3, â€”C(S)â€”R4, C(O)â€”Oâ€”R5, â€”C(O)â€”NHâ€”R6 or â€”C(S)â€”NHâ€”R7; whereby R3, R4, R5, R6 and R7, independently of one another, signify C1-C10-alkyl, acetoxy, C1-C10-haloalkyl, C1-C10-alkoxy or C1-C10-haloalkoxy, or independently of one another, denote unsubstituted phenyl or phenyl which is substituted once or many times by C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, halogen, cyano, hydroxyl, C1-C3-alkoxy, amino, CHO or nitro; R2 and R3, independently of one another, are hydrogen, C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, halogen, cyano, hydroxyl, amino, aryl or nitro; Ra denotes hydrogen, unsubstituted C1-C20-alkyl or C1-C20-alkyl which is substituted once or many times by halogen, cyano, hydroxyl, alkoxy, nitro, phenyl, biphenyl, benzyloxy or phenoxyphenyl, whereby each phenyl, biphenyl, benzyloxy or phenoxyphenyl in turn is unsubstituted or substituted once or many times by C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, C1-C3-alkoxy, halogen, cyano, hydroxyl, amino or nitro; or it denotes C3-C8-cycloalkyl, phenyl, biphenyl, phenoxyphenyl or heterocyclyl, whereby each of these cyclic radicals is unsubstituted or substituted once or many times by C1-C3-alkyl, C2-C6-alkenyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, C1-C3-alkoxy, halogen, cyano, hydroxyl, amino, (C1-C3-alkyl)2N, acetyl or nitro; or it denotes C-C6-alkylene-aryl , whereby the aryl radical is unsubstituted or substituted once or many times by C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, halogen, cyano, hydroxyl or nitro; or it denotes C1-C20-alkyl which, depending on the number of carbon atoms, is interrupted by oxygen at one or several positions; and Rb signifies hydrogen, C1-C20-alkyl, heterocyclyl or aryl, whereby each of the cyclic radicals is unsubstituted or substituted once or many times by C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-haloalkoxy, C2-C6-alkenyl, halogen, cyano, hydroxyl, C1-C3-alkoxy, amino,(C1-C3-alkyl)2N, or nitro; together with a spreading additive, to the skin, the pelt or the plumage of the warm-blooded animal.
