ALKYLTHIO-, ALKYLSULPHINYL- AND ALKYLSULPHONYLCARBAMATES AS HERBICIDES

摘要

Compounds of formula (I) in which R is halogen, C1-C3haloalkyl, cyano, nitro or C1-C3haloalkoxy; Z is hydrogen, halogen or together with R, -O-CF2-O-; R1 is C1-C5alkyl or C3-C6cycloalkyl; R2 and R3 independently of one another are hydrogen, C1-C4alkyl or C3-C6cycloalkyl; R4 is C1-C6alkyl, C2-C6alkenyl, C2-C6alkynyl, C3-C6cycloalkyl or C5- or C6-cycloalkenyl, or is C1-C4alkyl, C2-C6alkenyl, C2-C6alkynyl or C3-C6cycloalkyl, each of which is substituted by halogen, cyano, C1-C4alkyl-CO, phenyl-CO, COOR5, C1-C4alkoxy, C1-C4haloalkoxy, oxiranyl, dioxolanyl, tetrahydrofuranyl, tetrahydropyranyl, C3-C6cycloalkyl, halo-C3-C6-cycloalkyl, phenyl or phenoxy, it being possible for the phenyl group, in turn, to be substituted by halogen, C1-C3alkyl, C1-C4alkoxy, cyano or C1-C3haloalkyl, or is phenyl or phenyl which is substituted by halogen, C1-C3alkyl, C1-C4alkoxy, cyano or C1-C3haloalkyl; or R4 together with one of the R2 groups forms a C2-C6alkylene bridge; R5 is C1-C5alkyl or C3-C6cycloalkyl; n is the number 1, 2, or 3 and m is thenumber 0, 1 or 2; and the diastereomers and enantiomers of these compounds are suitable as herbicides.
