Patent

CA 2403563

The invention relates to novel pesticidally active .alpha.-sulfin- and .alpha.- sulfonamino acid amides of the general formula (I) including the optical isomers thereof and mixtures of such isomers, wherein n is a number zero or one; R1 - R9 have the meanings given in the specification R10 is either hydrogen, (a), (b), (c), (d) or (e) wherein R13, R14, R16, R17 and R19 are each independently hydrogen or C1-C4 alkyl, R15 is C4-C12 alkyl; C1-C12 halogenalkyl; C3-C8 cycloalkyl; optionally substituted aryl or optionally substituted heteroaryl, R18 is optionally substituted aryl or optionally substituted heteroaryl; and Z is oxygen, sulfur -CR20R21- or -NR22-, wherein R20, R21 and R22 independently of each other are hydrogen of C1-C4 alkyl; provided that when R8 is hydrogen, R9 is not C1-C6-alkoxy, C3-C6 alkenyloxy or C3-C6-alkynyloxy in position 3 of the phenyl ring carrying these radicals. The novel compounds possess plant-protecting properties and are suitable for protecting plants against infestation by phytopathogenic microorganisms.

Nouveaux amides d'acide .alpha.-sulfinaminé et .alpha.-sulfonaminé, à action pesticide, de formule générale (I), ainsi qu'isomères optiques desdits amides et mélanges desdits isomères. Dans cette formule, n représente 0 ou 1, R¿1? à R9 possèdent la signification figurant dans le descriptif, R¿10? représente hydrogène ou les formules (a), (b), (c), (d) ou (e), dans lesquelles R¿13?, R¿14?, R¿16?, R¿17? et R¿19? représentent chacun indépendamment hydrogène ou alkyle C¿1?-C¿4?, R¿15? représente alkyle C¿4?-C¿12?, halogénoalkyle C¿1?-C¿12?, cycloalkyle C¿3?-C¿8?, aryle éventuellement substitué ou hétéroaryle éventuellement substitué, R¿18? représente aryle éventuellement substitué ou hétéroaryle éventuellement substitué et Z représente oxygène, soufre, -CR¿20?R¿21?- ou -NR¿22?-, dans lesquelles R¿20?, R¿21? et R¿22? représentent indépendamment les uns des autres hydrogène ou alkyle C¿1?-C¿4?, à condition que lorsque R¿8? représente hydrogène, R¿9? ne soit pas alcoxy C¿1?-C¿6?, alcényloxy C¿3?-C¿6? ou alcynyloxy C¿3?-C¿6? en position 3 du noyau phényle portant ces radicaux. Ces nouveaux composés possèdent des propriétés phytoprotectrices et sont adaptés pour protéger des plantes contre les infestations par des micro-organismes pathogènes.
