摘要

O.Z. 0050/41033 Thiadiazabicyclononane derivatives of the formula I I (R1 = H, F; R2 = halogen; R3 = H, C1-C4-alkyl; R4 = H, C1-C8-alkoxy-carbonyl, C3-C6-alkenyloxycarbonyl or C3-C6-alkynyloxycarbonyl, and these 3 groups may additionally bear C1-C4-alkoxy; X, Y, Z = O, S; A = C2-C3-alkylene chain which in addition to R4 may bear up to 3 identical or different radicals R5: OH, COOH, C1-C4-alkyl or C1-C6-alkoxycarbonyl, and the last two radicals may in turn bear up to 5 halogen atoms or one of the following substituents: OH, CN, SH, C1-C4-alkoxy, C1-C6-alkylthio, C3-C6-alkenyloxy, C3-C6-alkenylthio, C3-C6-alkynyloxy, C3-C6-alkynylthio, C1-C6-alkylcarbonyloxy, C1-C6-alkoxycarbonyl, C1-C6-alkoxycarbonyl-C1-C4-alkoxy or C1-C6-alkoxycarbonyl-C1-C4-alkylthio). These thiadiazabicyclononane derivatives are suitable for use as herbicides.
