The mixture is stirred for 4.5 hours at room temperature, then concentrated on a rotary evaporator and the residue is taken up in 50 ml of ethyl acetate. It is washed with saturated sodium chloride solution, dried over magnesium sulfate and again concentrated on a rotary evaporator. The residue is purified by column chromatography on silica gel with hexane: ethyl acetate = 9: 1.
Yield: 1.8 g (6.1 mmol 61% of theory)

In analoger Weise werden die folgenden Verbindungen der Formel (I) hergestellt:The following compounds of the formula (I) are prepared in an analogous manner:
Die nachfolgenden Anwendungsbeispiele erläutern die Verwendbarkeit der erfindungsgemäßen Verbindungen.The following application examples explain the usability of the compounds of the invention.
Im Gewächshaus wurden die aufgeführten Pflanzenspezies vor dem Auflaufen mit den Verbindungen in einer Aufwandmenge von 0,3 kg Wirkstoff/ha behandelt. Die Verbindungen wurden zu diesem Zweck als Emulsion mit 500 Litern Wasser/ha gleichmäßig über den Boden versprüht. Hier zeigten zwei Wochen nach der Behandlung die erfindungsgemäßen Verbindungen eine hohe Kulturpflanzenselektivität in Zuckerrübe, Weizen, Mais und Sojabohne bei ausgezeichneter Wirkung gegen das Unkraut.In the greenhouse, the listed plant species were mixed with the Compounds treated at a rate of 0.3 kg of active ingredient / ha. The connections were for this purpose as an emulsion with 500 liters of water / ha evenly over the soil sprayed. Here two weeks after the treatment showed the invention Compounds have a high crop selectivity in sugar beet, wheat, maize and Soybean with excellent weed action.

Im Gewächshaus wurden die in der Tabelle aufgeführten Verbindungen durch Pipettieren auf eine Wasseroberfläche von ca. 170 cm² appliziert, wobei die Testpflanzen sowohl im Vorauflauf als auch im 1-3 Blattstadium eingesetzt wurden. Nach 2 Wochen zeigte sich, daß die erfindungsgemäßen Verbindungen gegen wichtige Reisunkräuter stark wirksam und gleichzeitig kulturpflanzenvertäglich sind.The compounds listed in the table were pipetted on in the greenhouse applied a water surface of about 170 cm², the test plants both in Pre-emergence as well as in the 1-3 leaf stage were used. After 2 weeks it turned out that the compounds according to the invention are very effective against important rice weeds and are crop compatible at the same time.
