摘要

The compounds of the general formula (I) below are suitable according to the invention as selective herbicides or plant growth regulators;;Wherein n is an integer from 0 to 6 and X is halogen, CN, OCN, SCN, C₂-C₄-/RTI alkynyl or CHR⁵R⁶And R⁵And R⁶Are independently of each other CN, NO₂, Formyl, optionally halo-substituted (C_One-C₄-alkyl) carbonyl, optionally halo-substituted (C_One-C₄-alkoxy)-carbonyl or an optionally substituted phenylcarbonyl, R^One RTI ID = 0.0 halo-substituted /RTI & _One-C₄-alkyl, optionally halo-substituted C RTI ID = 0.0 ₃-C₆-cycloalkyl or optionally substituted phenyl, R²Is halogen, CN, NO₂, C_One-C₃-alkyl, C_One-C₃-alkoxy, C_One-C₃-haloalkyl, C_One-C₃-haloalkoxy or R⁷S (O)_m-, R⁷C_One-C₃-alkyl, m is 0, 1 or 2, R³Is H, halogen, OH, C_One-C₃-alkyl, C_One-C₃-alkoxy, C_One-C₃-haloalkyl, C_One-C₃-haloalkoxy or (C_One-C₃-alkoxy) carbonyl, R⁴Is H, CN, NO₂, Halogen, C_One-C₃Haloalkyl,-C_One-C₃-haloalkoxy or R⁸S (O)_p-, R⁸C_One-C₃-alkyl /RTI and p is 0,1 or 2.;These compounds are novel except for compounds of the general formula (I) in which X is Cl.;They can be prepared from 2-benzoyl-1, 3-cyclohexanedione by various methods.
