4-PIRIDINYLMETHYLSULPHONAMIDE DERIVATIVES AS FUNGICIDAL PLANT PROTECTION AGENTS

摘要

The invention relates to sulphonamides of formula (I) in which the substituents have the following meanings: R1 = H, alkyl, alkoxy, alkenyl or alkinyl and R2, R3, R4, R5 = hydrogen, halogen, alkyl, alkoxy or halomethyl; R2 and R3 can also together form a phenyl, cyclopentyl, or cyclohexyl ring, whereby said ring can carry R2' and R3', where R2', R3' = H, halogen, alkyl, alkoxy or halomethyl; in the case a), when R2, R3, R4 and R5 = H, X = phenyl , substituted with a group -C(R6)=NOR7, where R6= alkyl and R7 = alkyl, benzyl , alkenyl, haloalkyl, haloalkenyl, alkinyl or haloalkinyl and in case b), when at least one of the groups R2, R3, R4 and R5 is not H, X = phenyl, naphthyl or a five- or six-membered saturated, partially unsaturated, or aromatic heterocycle, bonded by means of a C atom, comprising one to four heteroatoms from the group O, N or S, where X can be substituted as per the description. The invention further relates to methods for production of said compounds, agents comprising the same and use thereof for the control of fungal pests which are pathogenic to plants.
