Description
Gegenstand der Erfindung ist daher auch die Verwendung der Phenoxyphenoxycarbonsäurederivate der Formel (I) zur Unkrautbekämpfung. The invention therefore also relates to the use of the phenoxyphenoxycarboxylic acid derivatives of the formula (I) for weed control.
Herstellungsbeispiele Allgemeine Vorschrift zur Herstellung von Verbindungen der allgemeinen Formel I Preparation examples General instructions for the preparation of compounds of the general formula I
Beispiel 1 example 1
5 0,1 Mol Phenol (II) werden in 50 ml Methyläthylketon gelöst, 0,11 Mol Kaliumcarbonat (wasserfrei) zugesetzt und 0,11 Mol Halogencarbonsäureester (III) eingetropft. Dann wird ca. 16 Stunden am Rückfluss erhitzt. Danach wird mit Eiswasser versetzt, in Methylenchlorid aufgenommen, über Na2S04 getrocknet, das Lösungsmittel abdestilliert und das Rohprodukt gemäss der allgemeinen Formel (I) entweder zur Kristallisation gebracht oder im Vakuum destilliert. 5 0.1 mol of phenol (II) are dissolved in 50 ml of methyl ethyl ketone, 0.11 mol of potassium carbonate (anhydrous) is added and 0.11 mol of halocarboxylic acid ester (III) is added dropwise. Then the mixture is heated under reflux for about 16 hours. Then ice water is added, the mixture is taken up in methylene chloride, dried over Na2SO4, the solvent is distilled off and the crude product according to the general formula (I) is either crystallized or distilled in vacuo.
Beispiel 2 Example 2
15 0,1 Mol des Esters aus Beispiel 1 werden in 270 ml Methanol gelöst, dazu 24 ml 45%ige Natriumhydroxid-Lösung eingetropft und 2 Stunden am Rückfluss erhitzt. Danach wird das Lösungsmittel abdestilliert und die entsprechende Säure als Natriumsalz isoliert. Die freie Säure wird durch verdünnte 20 Salzsäure freigesetzt. 15 0.1 mol of the ester from Example 1 are dissolved in 270 ml of methanol, 24 ml of 45% sodium hydroxide solution are added dropwise and the mixture is heated under reflux for 2 hours. The solvent is then distilled off and the corresponding acid is isolated as the sodium salt. The free acid is released by dilute hydrochloric acid.
Beispiel 3 Example 3
0,1 Mol der Säure aus Beispiel 2 werden mit 80 ml Thio-nylchlorid versetzt und 6 Stunden am Rückfluss erhitzt. Da-25 nach wird der Überschuss an Thionylchlorid abdestilliert und das Säurechlorid in Toluol aufgenommen. 0.1 mol of the acid from Example 2 is mixed with 80 ml of thionyl chloride and heated under reflux for 6 hours. Then the excess of thionyl chloride is distilled off and the acid chloride is taken up in toluene.
Beispiel 4 Example 4
Zu 0,1 Mol eines Alkohols oder Phenols bzw. Merkaptans 30 oder Thiophenols, gelöst in 50 ml Toluol, werden 0,1 Mol Natriumhydroxid, gelöst in 50 ml Wasser, zugegeben. Bei etwa 25 bis 40 °C werden 0,1 Mol Säurechlorid aus Beispiel 3 in Toluol gelöst eingetropft. Nach etwa 1 Stunde wird die Toluoilösung abgetrennt, mit Wasser gewaschen und über Kaliumcarbonat 35 getrocknet. Nach Abdestillieren des Lösungsmittels wird das so gewonnene Rohprodukt entsprechend der allgemeinen Formel (I) zur Kristallisation gebracht oder destillativ gereinigt. 0.1 mol of sodium hydroxide, dissolved in 50 ml of water, is added to 0.1 mol of an alcohol or phenol or mercaptan 30 or thiophenol, dissolved in 50 ml of toluene. 0.1 mol of acid chloride from Example 3 dissolved in toluene is added dropwise at about 25 to 40 ° C. After about 1 hour, the toluene solution is separated off, washed with water and dried over potassium carbonate 35. After the solvent has been distilled off, the crude product obtained in this way is crystallized in accordance with the general formula (I) or purified by distillation.
Beispiel 5 Example 5
40 Zu 0,1 Mol Säurechlorid (gemäss Beispiel 3 hergestellt), gelöst in 50 ml Toluol, werden 0,1 Mol Triäthylamin zugesetzt. Bei 25 bis 40 °C werden dann 0,1 Mol eines aliphatischen Amins bzw. eines Anilins eingetropft. Man lässt 1 Stunde nachreagieren und setzt dann Wasser zu. Die Toluolphase wird 45 abgetrennt, mit Wasser gewaschen und über Natriumsulfat getrocknet. Nach Abdestillieren des Toluols wird das Amid bzw. Anilid isoliert. 40 0.1 mol of triethylamine are added to 0.1 mol of acid chloride (prepared according to Example 3), dissolved in 50 ml of toluene. 0.1 mol of an aliphatic amine or aniline are then added dropwise at 25 to 40 ° C. The mixture is left to react for 1 hour and then water is added. The toluene phase is separated off, washed with water and dried over sodium sulfate. After the toluene has been distilled off, the amide or anilide is isolated.

Anwendungsbeispiele Examples of use
Beispiel I Example I
Samen verschiedener Unkräuter und Kulturpflanzen wurden in Töpfen ausgesät. Ein Teil der Töpfe wurde sofort nach der Aussaat, ein Teil etwa 3 Wochen später, als die Pflanzen aufgelaufen waren und 3 bis 4 Blätter entwickelt hatten, mit in Wasser suspendierten Spritzpulverformulierungen erfindungs-gemässer Wirkstoffe behandelt. Seeds from various weeds and crops were sown in pots. Some of the pots were treated immediately after sowing, some about three weeks later, when the plants had emerged and had developed 3 to 4 leaves, with wettable powder formulations according to the invention suspended in water.
5 4 Wochen nach der Anwendung wurde das Ergebnis in Form visueller Bonituren nach dem Schema von BOLLE (vgl. Nachrichtenblatt des Deutschen Pflanzenschutzdienstes 16, 1964, 92-94) festgestellt: 5 4 weeks after the application, the result was determined in the form of visual ratings according to the BOLLE scheme (see news bulletin of the German Plant Protection Service 16, 1964, 92-94):

25 Das in Tabelle I angeführte Ergebnis lässt erkennen, dass die erfindungsgemässen Verbindungen Nr. 1 und Nr. 2 mit 2,5 kg/ha, z.T. auch mit geringerer Aufwandmenge, wichtige einjährige Unkräuter sowohl im Vor- als auch in Nachauflauf-Verfahren kontrollieren. Die hier genannten Unkräuter 30 gehören alle der botanischen Familie Gramineae (Gräser) an. Wichtige Kulturpflanzen wurde zur gleichen Zeit geschont. 25 The result shown in Table I shows that the compounds No. 1 and No. 2 according to the invention with 2.5 kg / ha, in part. Control important annual weeds both in the pre- and post-emergence process, even with a lower application rate. The weeds 30 mentioned here all belong to the botanical family Gramineae (grasses). Important crops were spared at the same time.

In Töpfen mit geschlossenem Boden wurden Samen von Echinochloa crus-galli (Hühnerhirse) ausgesät. Zur gleichen Zeit wurden 14 Tage alte Reis-Pflanzen in Töpfe desselben Echinochloa crus-galli (millet) seeds were sown in pots with a closed base. At the same time, 14 day old rice plants were placed in pots of the same
