The present invention relates to substituted 1,2,5-oxadiazole compounds of the formula (I) and the N-oxides and salts thereof and to compositions comprising the same. The invention also relates to the use of the 1,2,5-oxadiazole compounds or of the compositions comprising such compounds for controlling unwanted vegetation. Furthermore, the invention relates to methods of applying such compounds. In formula I, the variables have the following meanings: R is e.g. hydrogen, cyano, nitro, halogen, C1-C6-alkyl, C3-C7-cycloalkyl, C3-C7-cycloalkyl-C1-C4-alkyl, C1-C6-haloalkyl, C2-C6-alkenyl, C2-C6-haloalkenyl, C2-C6-alkynyl, C2-C6-haloalkynyl, C1-C4-alkoxy-C1-C4-alkyl, C1-C4-haloalkoxy-C1-C4-alkyl, O-Ra, Z-S(O)n-Rb, Z-C(=O)-Rc, Z-C(=O)-ORd, Z-C(=O)-NReRf, Z-NRgRh, Z-phenyl or Z-heterocyclyl;CYC is a bi- or tricyclic radical of the following formulae Cyc-1 or Cyc-2 where # is the point of attachment of the bicyclic radical to the carbonyl group, Q, Q' independently of each other are e.g. a fused 5-, 6-, 7-, 8-, 9- or 10-membered carbocycle or a fused 5-, 6-, 7-, 8-, 9- or 10-membered heterocycle; R1 is e.g. Z1-cyano, halogen, nitro, C1-C8-alkyl, C2-C8-alkenyl, C2-C8-alkynyl, C1-C8-haloalkyl, C1-C8-alkoxy, C1-C4-alkoxy-C1-C4-alkyl, Z1-C1-C4-alkoxy-C1-C4-alkoxy, C1- C4-alkylthio-C1-C4-alkyl, Z1-C1-C4-alkylthio-C1-C4-alkylthio, C2-C6-alkenyloxy, C2-C6- alkynyloxy, C1-C6-haloalkoxy, C1-C4-haloalkoxy-C1-C4-alkyl, Z1-C1-C4-haloalkoxy-C1-C4- alkoxy, Z1-S(O)k-R1b, Z1-phenoxy or Z1-heterocyclyloxy; R3 is e.g. hydrogen, halogen, Z3-OH, Z3-NO2, Z3-cyano, C1-C6-alkyl, C2-C8- alkenyl, C2-C8-alkynyl, Z2-C3-C10-cycloalkyl, Z3-C3-C10-cycloalkoxy, C1-C8-haloalkyl, Z3-C1-C8-alkoxy, Z3-C1-C8-haloalkoxy, Z3-C1-C4-alkoxy-C1-C4-alkoxy, Z3-C1-C4-alkylthio-C1-C4-alkylthio, Z3-C2-C8-alkenyloxy, Z3-C2-C8-alkynyloxy, Z3-C1-C8-haloalkoxy, Z3-C2-C8- haloalkenyloxy, Z3-C2-C8-haloalkynyloxy, Z3-C1-C4-haloalkoxy-C1-C4-alkoxy, Z3-(tri-C1- C4-alkyl)silyl, Z3-S(O)k-R3b, Z3-C(=O)-R3c, Z3-C(=O)-OR3d, Z3-C(=O)-NR3eR3f, Z3- NR3gR3h, Z3a-phenyl or Z3a-heterocyclyl; R4 is hydrogen, halogen, cyano, nitro, C1-C4-alkyl or C1-C4-haloalkyl; R5 is hydrogen, halogen, C1-C4-alkyl or C1-C4-haloalkyl; provided that at least one of the radicals R4 and R5 is different from hydrogen; n is 0, 1 or 2; k is 0, 1 or 2; and the variables Z, Z1, Z2, Z3, Z3a, Ra, Rb, R1b, R2b, R3b, Rc, R2c, R3c, Rd, R3d, Re, Rf, R3e, R3f, Rg, Rh, R2g, R2h, R3g and R3h have the meanings given in the claims. |
