Zusammenfassung:Thiadiazabicyclononane derivatives of the formula I I (R1=H, F; R2=halogen; R3=H, C1-C4-alkyl; R4=H, C1-C8-alkoxycarbonyl, C3-C6-alkenyloxycarbonyl or C3-C5-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.
