Verbindungen der Formel I, in denen Z = -C=N-W-R10 bedeutet und die als Oxime oder Schiff sehe Basen von Aldehyden der Formel I (Z = -CHO) aufzufas-s sen sind, erhält man durch Umsetzung dieser Aldehyde mit Aminen oder Hydroxylaminen der Formel H2N-W-R10 (IV) unter den bekannten Bedingungen für die Herstellung von SchifFschen Basen und Oximen. Für W = Sauerstoff kann man auch Verbindungen der Formel I mit Z io = -HC=N-OH mit Verbindungen der Formel B-Rj 0 (B = Halogen, vorzugsweise Chlor o'der Brom) zu den gewünschten Verbindungen umsetzen. Compounds of the formula I in which Z = -C = NW-R10 and which are to be regarded as oximes or Schiff bases of aldehydes of the formula I (Z = -CHO) are obtained by reacting these aldehydes with amines or Hydroxylamines of the formula H2N-W-R10 (IV) under the known conditions for the production of SchifF bases and oximes. For W = oxygen, compounds of the formula I with Z io = -HC = N-OH can also be reacted with compounds of the formula B-Rj 0 (B = halogen, preferably chlorine or bromine) to give the desired compounds.
Für die Herstellung der in einigen Fällen als Ausgangsstoffe verwendeten Säureamide und Säurechloride kommen i5 an sich bekannte Verfahren in Betracht. For the production of the acid amides and acid chlorides used in some cases as starting materials, processes known per se can be used.
Die Verbindungen der Formel I sind gegen ein breites Spektrum von Schadgräsern herbizid wirksam, wobei gleichzeitig diese Verbindungen von zweikeimblättrigen Kulturpflanzen sowie zum Teil auch von verschiedenen Getreidear-20 ten gut toleriert werden. Damit sind die Verbindungen der Formel I zur selektiven Bekämpfung von Schadgräsern in Kulturpflanzen geeignet. The compounds of the formula I are herbicidally active against a broad spectrum of harmful grasses, and at the same time these compounds are well tolerated by dicotyledonous crop plants and in some cases also by various types of cereals. The compounds of the formula I are therefore suitable for the selective control of harmful grasses in crop plants.

Emulgierbare Konzentrate werden durch Auflösen des Wirkstoffes in einem organischen Lösungsmittel, z. B. Buta-nol, Cyclohexanon, Dimethylformamid, Xylol oder auch höhersiedenden Aromaten erhalten. Emulsifiable concentrates are obtained by dissolving the active ingredient in an organic solvent, e.g. B. butanol, cyclohexanone, dimethylformamide, xylene or higher-boiling aromatics.
40 Stäubemittel erhält man durch Vermählen des Wirkstoffes mit fein verteilten, festen Stoffen, z.B. Talkum, natürlichen Tonen, wie Kaolin, Bentonit, Pyrophillit oder Diatomeenerde. 40 dusts are obtained by grinding the active ingredient with finely divided, solid substances, e.g. Talc, natural clays, such as kaolin, bentonite, pyrophillite or diatomaceous earth.
Versprühbare Lösungen, wie sie vielfach in Sprühdosen 45 gehandelt werden, enthalten den Wirkstoff in einem organischen Lösungsmittel gelöst, daneben befindet sich z.B. als Treibmittel ein Gemisch von Fluorchlorkohlenwasserstoffen. Sprayable solutions, as are often traded in spray cans 45, contain the active ingredient dissolved in an organic solvent, next to it is e.g. a mixture of chlorofluorocarbons as blowing agent.
Granulate können entweder durch Verdüsen des Wirk-50 stoffes auf adsorptionsfähiges, granuliertes Inertmaterial hergestellt werden oder durch Aufbringen von Wirkstoffkonzentraten mittels Klebemitteln, z. B. Polyvinylalkohol, polyacrylsaurem Natrium oder auch Mineralölen auf die Oberfläche von Trägerstoffen, wie Sand, Kaolinite, oder von 55 granuliertem Inertmaterial. Auch können geeignete Wirkstoffe in der für die Herstellung von Düngemittelgranalien üblichen Weise - gewünschtenfalls in Mischung mit Düngemitteln - hergestellt werden. Granules can either be produced by spraying the active substance onto adsorbable, granulated inert material or by applying active substance concentrates by means of adhesives, e.g. B. polyvinyl alcohol, sodium polyacrylic acid or mineral oils on the surface of carriers such as sand, kaolinite, or 55 granulated inert material. Suitable active substances can also be produced in the manner customary for the production of fertilizer granules - if desired in a mixture with fertilizers.

Zur Anwendung werden die handelsüblichen Konzentrate gegebenenfalls in üblicher Weise verdünnt, z.B. bei benetzbaren Pulvern und emulgierbaren Konzentraten mittels s Wasser. Staubförmige und granulierte Zubereitungen sowie versprühbare Lösungen werden vor der Anwendung nicht mehr mit weiteren inerten Stoffen verdünnt. Mit den äusseren Bedingungen wie Temperatur, Feuchtigkeit u.a. variiert die erforderliche Aufwandmenge. Sie kann innerhalb io weiter Grenzen schwanken, z.B. zwischen 0,1 kg/ha und 10 kg/ha Aktivsubstanz, liegt jedoch vorzugsweise zwischen 0,3 und 3 kg/ha. For use, the commercially available concentrates are optionally diluted in the customary manner, e.g. for wettable powders and emulsifiable concentrates using s water. Dust-like and granulated preparations and sprayable solutions are no longer diluted with other inert substances before use. With the external conditions such as temperature, humidity, etc. the required application rate varies. It can fluctuate within wide limits, e.g. between 0.1 kg / ha and 10 kg / ha of active substance, but is preferably between 0.3 and 3 kg / ha.

Beispiel 38 2-[4'-(2",4"-Dichlorphenoxy)-phenoxy]-propanal-N-propylimin 15 g (0,036 Mol) des in Beispiel (28) erhaltenen Bisulfit-addukts werden in einem Gemisch von 100 ml Essigsäureäthylester und 50 ml 1-n-Schwefelsäure unter Stickstoff so lange bei 60 °C gerührt, bis die Entwicklung von Schwefeldioxid abgeschlossen ist. Die organische Phase wird mit Bicarbonatlösung neutralisiert. Die so erhaltene Lösung des Aldehyds in Essigsäureäthylester wird unter Stickstoff zu einer Lösung von 2,95 g (0,05 Mol) Propylamin in 50 ml Essigsäureäthylester unter äusserem Kühlen zugetropft. Das Reaktionsgemisch bleibt 12 Stunden bei Raumtemperatur stehen. Essigsäureäthylester wird unter Vakuum abdestilliert. Der verbleibende Rückstand wird säulenchromatogra-phisch von anhängenden Verunreinigungen befreit. Man erhält 9,6 g (76% d.Th.) an 2-[4'-(2",4"-Dichlorphenoxy)-phenoxy]-propanal-N-propylimin. Example 38 2- [4 '- (2 ", 4" -dichlorophenoxy) phenoxy] propanal-N-propylimine 15 g (0.036 mol) of the bisulfite adduct obtained in Example (28) are mixed in a mixture of 100 ml of ethyl acetate and 50 ml of 1-n-sulfuric acid were stirred under nitrogen at 60 ° C. until the evolution of sulfur dioxide was complete. The organic phase is neutralized with bicarbonate solution. The solution of the aldehyde in ethyl acetate thus obtained is added dropwise under nitrogen to a solution of 2.95 g (0.05 mol) of propylamine in 50 ml of ethyl acetate with external cooling. The reaction mixture remains at room temperature for 12 hours. Ethyl acetate is distilled off under vacuum. The remaining residue is freed of any attached impurities by column chromatography. 9.6 g (76% of theory) of 2- [4 '- (2 ", 4" -dichlorophenoxy) phenoxy] propanal-N-propylimine are obtained.

Samen von Gräsern wurden in Töpfen ausgesät und die als Spritzpulver formulierten erfindungsgemässen Präparate in verschiedenen Dosierungen auf die Erdoberfläche gesprüht. Anschliessend wurden die Töpfe für 4 Wochen in einem Gewächshaus aufgestellt. Das Resultat der Behandlung (ebenso auch bei den folgenden Beispielen) wurde durch eine Bonitierung nach dem Schema von Bolle (Nachtrichtenblatt des Deutschen Pflanzenschutzdienstes 16,1964,92-94 ermittelt: Seeds of grass were sown in pots and the preparations according to the invention formulated as wettable powder were sprayed onto the surface of the earth in various dosages. The pots were then placed in a greenhouse for 4 weeks. The result of the treatment (also in the following examples) was determined by a rating according to the Bolle scheme (Nachtsichtenblatt des Deutschen Plantenschutzdienstes 16, 1964, 92-94:

Wirkung der Präparate bonitiert. Auch hier dienten Fluoro-difen und Mecoprop als herbizide Vergleichsmittel. Die beanspruchten Verbindungen waren bei diesem Applikationsverfahren zwar etwas schwächer wirksam als bei dem in Beispiel 1 beschriebenen Vorauflaufverfahren, jedoch waren sie besser gegen Gräser wirksam als die beiden Vergleichsmittel (Tab. II). Eine ähnliche Wirkung gegen Gräser zeigten ferner die beanspruchten Verbindungen aus Beispielen 1,10,23,26, 27. Effect of the preparations rated. Here, too, fluoro-difen and mecoprop served as comparative herbicides. The claimed compounds were somewhat less effective in this application process than in the pre-emergence process described in Example 1, but they were more effective against grasses than the two comparison agents (Table II). The claimed compounds from Examples 1, 10, 23, 26, 27 also showed a similar activity against grasses.
Beispiel III Example III
In einem weiteren Versuch wurden Verbindungen der Formel I vor dem Auflaufen in zahlreichen Kulturpflanzen angewendet. Die Auswertung ergab (vgl. Tabelle III), dass alle geprüften zweikeimblättrigen (dikotylen) Kulturarten Behandlungen mit 2,5 kg/ha 4, 2,9 und 8 tolerierten. Dasselbe gilt auch für Zwiebeln. In a further experiment, compounds of the formula I were used in numerous crop plants before emergence. The evaluation showed (see Table III) that all tested dicotyledonous (dicotyledon) crops tolerated treatments with 2.5 kg / ha 4, 2.9 and 8. The same applies to onions.
Darüber hinaus blieben auch Weizen und Gerste bei Anwendung der Verbindungen gemäss Beispielen 4 und 9 unge-schädigt. In addition, wheat and barley also remained undamaged when the compounds according to Examples 4 and 9 were used.
