<p>Cyclohexenone derivatives of the general formula I <IMAGE> in which the substituents have the following meaning: R<1> is optionally substituted C1-C6-alkyl, C3-C6-alkenyl or C3-C6-alkynyl, phenyl, benzyl or thenyl; R<2> is optionally substituted C1-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl or phenyl; R3 is hydrogen, C1-C6-alkyl, C1-C10-alkylcarbonyl, C1-C6-alkylsulphonyl, C1-C4-trialkylsilyl, C1-C4-dialkylphosphonyl, C1-C4-dialkylthiophosphonyl, C3-C6-alkenyl, C3-C6-alkenylcarbonyl, C3-C6-alkynyl, optionally substituted benzoyl or phenylsulphonyl; R<4> is hydrogen, cyano, halogen, C1-C6-alkyl or C1-C6-alkoxycarbonyl; A is an optionally substituted C1-C4-alkylene chain in which one methylene group can be replaced by an oxygen or sulphur atom; m is 0 or 1; B is a 5-membered singly or doubly unsaturated heterocycle having up to 2 nitrogen atoms and/or up to one oxygen or sulphur atom; X is 3-7-membered cycloalkyl or 5-7-membered cycloalkenyl, it being possible for a methylene group in these to have been replaced by an oxygen or sulphur atom; optionally substituted phenyl or 5-6-membered heteroaryl, and if B denotes isoxazolinyl, also hydrogen; Y is hydrogen, halogen, cyano, nitro; optionally substituted C1-C6-alkyl, C2-C6-alkenyl or C2-C6-alkynyl; C1-C4-alkoxy, C1-C4-alkylthio, C3-C6-alkenyloxy or C3-C6-alkynyloxy; n is 1, 2 or 3; where Y does not denote hydrogen if m = 0, B = isoxazol-5-yl and X = 3-(C3-C6-cycloalkyl), and their environmentally tolerable salts, processes for their preparation and their use as herbicidal agents.</p> |
