  • the invention also relates to compositions which contain the compounds of the formula I, to the use of the compounds I and compositions containing them for combating harmful plants, to new benzoylpyrazoles of the formula II and to a process for the preparation of the compounds I and II.
  • Herbicidally active 4-benzoyl-pyrazoles are known from the literature, for example from EP-A 282 944 or WO 96/26206.
  • EP-A 282 944 only mentions generally that the reaction of 4-benzoyl -5-hydroxypyrazoles with acid halides should lead to 4-benzoyl -5-chloropyrazoles.
  • Benzylidenpyrazolone with z. T. herbicidal activity are known from US 4,382,948 and JP 61268670. All previous structures have a very specific substitution pattern in the phenyl part of benzylidene pyrazolone: for example, there is always a hydrogen or halogen atom or a trifluoromethyl or nitro group in the para position to the methine bridge.
  • the present invention also relates to stereoisomers of the compounds of the formula I. Both pure stereoisomers and mixtures thereof are covered.
  • the compounds of the formula I can exist as eis or trans isomers and, depending on the substitution pattern, can contain one or more chirality centers and can then also exist as enantiomers or mixtures of diastereomers.
  • the invention relates both to the pure isomers, enantiomers or diastereomers and to mixtures thereof.

  • the benzylidene pyrazolones Ib can preferably be obtained from ketones of the formula V, which are either known or can be prepared analogously to known compounds (see DE-A 19709118.0 and WO 96/26200), by reaction with acid halides.
  • Suitable acid halides are the halides of sulfuric acid, carbonic acid and phosphoric acid.
  • phosphorus oxybromide is preferably used.
  • the reaction can be carried out in the customary manner, either without or with a solvent which is inert under the reaction conditions.
  • the selectivity of the reaction can generally be controlled by adding a base which is not very nucloephilic, for example pyridine, dirnethylaminopyridine or dimethylformamide.
  • the reaction temperature is usually 0 ° C to 200 ° C, preferably 50 ° C to 140 ° C.
  • both isomers can be obtained on the newly formed double bond in the mixture.
  • the isomers can be separated if necessary (e.g. by crystallization, extraction or chromatography).
  • a by-product of this reaction are the compounds II, which, depending on the substitution pattern and reaction procedure, can be obtained in smaller, comparable or predominant proportions. In many cases, these compounds are new and of considerable interest as precursors for herbicidal active compounds (see, for example, EP-A 282 944).
