Compounds of formula (1), where: Q is a group moiety of formula (2); A is a bridge group member of formulas (3) to (7), where members of the group of formulas (3) to (7) are linked to group Q at the carrying end of the oxygen atom; B is either a direct bond between the sp-hybridized carbon atom of the triple bond of the phenyl ring or is a bridge member of the group moiety of formula (8), where R, R1, R2, R131, R132, R133, R134 , R135, R136, R137, R138, R139 and R140, R141, R142, R143, R144, R145, R146, R147 and R148 and the n and n subfixes are as defined in claim 1, and also the N-oxides of rest of the group of formula (2), the agrochemically acceptable salts and all stereoisomers and tautomers of the formula (1), with the proviso that, when B is a direct bond between the sp-hybridized triple bond carbon atom and The phenyl ring, the bridge member A is different from the formula (3), are suitable for use as herbicides. |
