- 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.
- benzylidene pyrazolones of the formula I and benzoylpyrazoles of the formula II can be prepared as described below.
- Benzylidene pyrazolones of the formula Ia hydrogen
- X hydrogen
- Benzylidene pyrazolones of the formula Ia can be obtained by Knoevenagel condensation of pyrazolones of the formula III, in which the radicals R 1 and R 7 have the abovementioned meaning, and a substituted benzaldehyde of the formula IV, in which the radicals R 2 to R 4 have the abovementioned meaning, can be synthesized analogously to the method described in US 4,382,948.
- 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).

Aus der Literatur, beispielsweise aus EP-A 282 944 oder WO 96/26206 sind herbizid wirksame 4 -Benzoyl -pyrazole bekannt.Herbicidally active 4-benzoyl-pyrazoles are known from the literature, for example from EP-A 282 944 or WO 96/26206.
4-Benzoyl-5-chlor-pyrazole sind bisher jedoch nicht beschrieben. In der EP-A 282 944 wird lediglich allgemein erwähnt, daß die Umsetzung von 4 -Benzoyl -5-hydroxypyrazolen mit Säurehalogeniden zu 4 -Benzoyl -5-chlor-pyrazolen führen sollte.However, 4-benzoyl-5-chloropyrazoles have not yet been described. 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 mit z. T. herbizider Wirkung sind aus US 4,382,948 und JP 61268670 bekannt. Alle bisherigen Strukturen weisen im Phenylteil des Benzylidenpyrazolons eine ganz spezifisches Substitutionsmuster auf: in para-Stellung zur Methinbrücke sitzt beispielsweise stets ein Wasserstoff- oder Halogenatom bzw. eine Trifluormethyl- oder Nitro-Gruppe.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.
Die herbiziden Eigenschaften der bisher bekannten Verbindungen sowie die Verträglichkeiten gegenüber Kulturpflanzen können jedoch nur bedingt befriedigen. Es lag daher dieser Erfindung die Aufgabe zugrunde, neue, insbesondere herbizid wirksame, Verbindungen mit verbesserten Eigenschaften zu finden.However, the herbicidal properties of the compounds known hitherto and the tolerances to crop plants can only satisfy to a limited extent. It was therefore the object of this invention to find new, in particular herbicidally active, compounds with improved properties.
Demgemäß wurden die erfindungsgemäßen Benzylidenpyrazolone der Formel I sowie deren herbizide Wirkung gefunden.We have found that this object is achieved by the benzylidene pyrazolones of the formula I and their herbicidal activity.
Gegenstand der vorliegenden Erfindung sind auch Stereoisomere der Verbindungen der Formel I. Es werden sowohl reine Stereoisomere als auch Gemische hiervon erfaßt.
Die Verbindungen der Formel I können als eis- oder trans-Isomere vorliegen und je nach Substitutionsmuster ein oder mehrere Chira- litätszentren enthalten und können dann auch als Enantiomeren oder Diastereomerengemische vorliegen. Gegenstand der Erfindung sind sowohl die reinen Isomere, Enantiomere oder Diastereomere als auch deren Gemische.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.
Die erfindungsgemäßen Benzylidenpyrazolone der Formel I und Benzoylpyrazole der Formel II lassen sich wie im folgenden beschrieben herstellen.The benzylidene pyrazolones of the formula I and benzoylpyrazoles of the formula II can be prepared as described below.
Benzylidenpyrazolone der Formel Ia (X = Wasserstoff) lassen sich durch Knoevenagel-Kondensation von Pyrazolonen der Formel III, in der die Reste R1 und R7 die vorgenannte Bedeutung haben, und einem substituierten Benzaldehyd der Formel IV, in der die Reste R2 bis R4 die vorgenannte Bedeutung haben, analog der in US 4,382,948 beschriebenen Methode synthetisieren.Benzylidene pyrazolones of the formula Ia (X = hydrogen) can be obtained by Knoevenagel condensation of pyrazolones of the formula III, in which the radicals R 1 and R 7 have the abovementioned meaning, and a substituted benzaldehyde of the formula IV, in which the radicals R 2 to R 4 have the abovementioned meaning, can be synthesized analogously to the method described in US 4,382,948.

Desweiteren sind die Verbindungen Ia z. B. durch reduktive Dehalogenierung aus Verbindungen der Formel I, in denen X Brom bedeutet, zugänglich.Furthermore, the compounds Ia z. B. accessible by reductive dehalogenation from compounds of formula I in which X is bromine.
Benzylidenpyrazolone Ib (X = Brom oder Chlor) können durch Halo- genierung der zuvor beschriebenen Verbindungen Ia mit Brom oder Chlor und anschließende Dehydrohalogenierung in Gegenwart von Base hergestellt werden.Benzylidene pyrazolones Ib (X = bromine or chlorine) can be prepared by halogenation of the compounds Ia described above with bromine or chlorine and subsequent dehydrohalogenation in the presence of base.
Vorzugsweise lassen sich die Benzylidenpyrazolone Ib aus Ketonen der Formel V, die entweder bekannt sind oder analog zu bekannten Verbindungen hergestellt werden können (s. DE-A 19709118.0 und WO 96/26200) , durch Umsetzung mit Säurehalogeniden gewinnen.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.
Als Säurehalogenide kommen beispielsweise die Halogenide der Schwefelsäure, Kohlensäure und Phosphorsäure in Betracht. Für den Austausch gegen Chlor wird bevorzugt Thionylchlorid, Phosgen, Phosphorpentachlorid und besonders bevorzugt Phosphoroxychlorid
eingesetzt. Für den Austausch gegen Brom wird bevorzugt Phos - phoroxybromid verwendet.Examples of suitable acid halides are the halides of sulfuric acid, carbonic acid and phosphoric acid. For the exchange for chlorine, preference is given to thionyl chloride, phosgene, phosphorus pentachloride and particularly preferably phosphorus oxychloride used. For the exchange for bromine, phosphorus oxybromide is preferably used.
Die Umsetzung kann dabei in üblicher Weise, entweder ohne oder mit einem unter den Reaktionsbedingungen inerten Lösungsmittel erfolgen. Die Selektivität der Reaktion läßt sich im allgemeinen durch Zugabe einer wenig nukloephilen Base wie beispielsweise Pyridin, Dirnethylaminopyridin, Dimethylformamid steuern.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.
Die Reaktionstemperatur beträgt in der Regel 0°C bis 200°C, vorzugsweise 50°C bis 140°C.The reaction temperature is usually 0 ° C to 200 ° C, preferably 50 ° C to 140 ° C.

Bei dieser Reaktion können beide Isomere an der neu gebildeten Doppelbindung im Gemisch anfallen. In diesen Fall können die Isomere bei Bedarf getrennt werden (z.B. durch Kristallisation, Extraktion oder Chromatographie) .In this reaction, both isomers can be obtained on the newly formed double bond in the mixture. In this case, the isomers can be separated if necessary (e.g. by crystallization, extraction or chromatography).
Ein Nebenprodukt dieser Reaktion sind die Verbindungen II, die je nach Substitutionsmuster und Reaktionsführung in geringeren, vergleichbaren oder überwiegenden Anteilen anfallen können. Diese Verbindungen sind in vielen Fällen neu und als Vorprodukte für herbizide Wirkstoffe von erheblichem Interesse (siehe z B. EP-A 282 944) .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).

AnwendungsbeispieleExamples of use
Die herbizide Wirkung der Benzylidenpyrazolone der Formel I ließ sich durch Gewächshausversuche zeigen:
Als Kulturgefäße dienten Plastiktöpfe mit lehmigem Sand mit etwa 3,0 % Humus als Substrat. Die Samen der Testpflanzen wurden nach Arten getrennt eingesät.The herbicidal activity of the benzylidene pyrazolones of the formula I was demonstrated by greenhouse experiments: Plastic pots with loamy sand with about 3.0% humus as substrate served as culture vessels. The seeds of the test plants were sown separately according to species.
Bei Vorauflaufbehandlung wurden die in Wasser suspendierten oder emulgierten Wirkstoffe direkt nach Einsaat mittels fein verteilender Düsen aufgebracht. Die Gefäße wurden leicht beregnet, um Keimung und Wachstum zu fördern, und anschließend mit durchsichtigen Plastikhauben abgedeckt, bis die Pflanzen angewachsen waren. Diese Abdeckung bewirkt ein gleichmäßiges Keimen der Test- pflanzen, sofern dies nicht durch die Wirkstoffe beeinträchtigt wurde .In pre-emergence treatment, the active ingredients suspended or emulsified in water were applied directly after sowing using finely distributing nozzles. The tubes were lightly sprinkled to promote germination and growth, and then covered with clear plastic hoods until the plants had grown. This cover causes the test plants to germinate evenly, unless this was affected by the active ingredients.
Zum Zweck der Nachauflaufbehandlung wurden die Testpflanzen je nach Wuchsform erst bis zu einer Wuchshöhe von 3 bis 15 cm angezogen und dann mit den in Wasser suspendierten oder emulgierten Wirkstoffen behandelt. Die Testpflanzen wurden dafür entweder direkt gesät und in den gleichen Gefäßen aufgezogen oder sie wurden erst als Keimpflanzen getrennt angezogen und einige Tage vor der Behandlung in die Versuchsgefäße verpflanzt. Die Aufwandmenge für die Nachauflaufbehandlung betrug 0.125 bzw. 0.0625 kg/ha a.S.For the purpose of post-emergence treatment, the test plants were first grown to a height of 3 to 15 cm, depending on the growth habit, and then treated with the active ingredients suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers or they were first grown separately as seedlings and transplanted into the test containers a few days before the treatment. The application rate for post-emergence treatment was 0.125 and 0.0625 kg / ha a.S.
Die Pflanzen wurden artenspezifisch bei Temperaturen von 10 - 25°C bzw. 20 - 35°C gehalten. Die Versuchsperiode erstreckte sich über 2 bis 4 Wochen. Während dieser Zeit wurden die Pflanzen gepflegt, und ihre Reaktion auf die einzelnen Behandlungen wurde ausgewertet.The plants were kept at temperatures of 10 - 25 ° C or 20 - 35 ° C depending on the species. The trial period lasted 2 to 4 weeks. During this time, the plants were cared for and their response to each treatment was evaluated.
Bewertet wurde nach einer Skala von 0 bis 100. Dabei bedeutet 100 kein Aufgang der Pflanzen bzw. völlige Zerstörung zumindest der oberirdischen Teile und 0 keine Schädigung oder normaler Wachstumsverlauf .Evaluation was carried out on a scale from 0 to 100. 100 means no emergence of the plants or complete destruction of at least the aerial parts and 0 means no damage or normal growth.
In den Gewächshausversuchen wurden im Nachauflaufverfahren die folgenden Pflanzen verwendet:
The following plants were used in the post-emergence greenhouse experiments:
Das Ergebnis zeigte, daß mit Verbindung Nr. 1.119 die obengenann¬ ten Schadpflanzen sehr effektiv bekämpft werden (> 98 % Schädi¬ gung der Pflanzen) während die Nutzpflanze Mais durch die Behand- lung keine sichtbaren Schäden (0 % Schädigung) davontrug.The result showed that with compound no. 1.119, the above genann ¬ th weeds very effectively combated (> 98% material injury ¬ plant supply) during the crop corn by the treatment no visible damage (0% damage) carried off.
