where W is hydrogen, fluorine or chlorine and m is 1 or 2, and the other is fluorine, chlorine or bromine or a group of the formula °=c:60&udf54;&udf53;vu10&udf54;&udf53;vz5&udf54;&udf53;vu10&udf54;where X, Y and Z are independently hydrogen, fluorine or chlorine, and R³ is hydrogen or a cyano or ethynyl group.
Diese Verbindungen besitzen sehr gute insecticide Eigenschaften und eine gute Beständigkeit gegenüber Abbau durch Licht. Durch letztere Eigenschaft unterscheiden sie sich von ähnlichen natürlich vorkommenden Cyclopropancarbonsäurederivaten, von denen seit langem bekannt ist, daß sie insecticide Eigenschaften besitzen.These compounds possess very good insecticidal properties and good stability to photodegradation. The latter property distinguishes them from similar naturally occurring cyclopropanecarboxylic acid derivatives, which have long been known to possess insecticidal properties.
Ein Verfahren, das sich zur Herstellung der in der genannten Patentschrift beschriebenen Verbindungen eignet, besteht darin, daß ein Niederalkylester der Formel II °=c:90&udf54;&udf53;vu10&udf54;&udf53;vz8&udf54; &udf53;vu10&udf54;worin R&sup4; für Niederalkyl mit bis zu 6 Kohlenstoffatomen, vorzugsweise Methyl oder Äthyl, steht und R¹ und R² die oben angegebenen Bedeutungen besitzen, mit einem Alkohol der Formel III °=c:50&udf54;&udf53;vu10&udf54;&udf53;vz4&udf54; &udf53;vu10&udf54;zur Bewirkung einer Umesterungsreaktion erhitzt wird.A process suitable for preparing the compounds described in the cited patent specification comprises heating a lower alkyl ester of the formula II °=c:90&udf54;&udf53;vu10&udf54;&udf53;vz8&udf54;&udf53;vu10&udf54;wherein R⁴ is lower alkyl having up to 6 carbon atoms, preferably methyl or ethyl, and R¹ and R² have the meanings given above, with an alcohol of the formula III °=c:50&udf54;&udf53;vu10&udf54;&udf53;vz4&udf54;&udf53;vu10&udf54;to effect a transesterification reaction.
Die im vorstehenden Patentanspruch 1 definierten Verbindungen der Formel (IV) eignen sich als Zwischenprodukte zur Herstellung der Verbindungen der obigen Formel (II). Letztere können aus den erfindungsgemäßen Verbindungen dadurch erhalten werden, daß man eine erfindungsgemäße Verbindung mit einem Diazoessigsäureniederalkylester umsetzt. Das Verfahren wird zweckmäßig unter Verwendung eines Überschusses des Diens als Lösungsmittel für den Diazoessigsäureniederalkylester in Gegenwart eines Metallkatalysators, wie z. B. pulverisiertes Kupfer oder pulverisierte Kupferbronze, ausgeführt.The compounds of formula (IV) defined in the preceding claim 1 are suitable as intermediates for the preparation of the compounds of formula (II) above. The latter can be obtained from the compounds according to the invention by reacting a compound according to the invention with a lower alkyl diazoacetate. The process is conveniently carried out using an excess of the diene as solvent for the lower alkyl diazoacetate in the presence of a metal catalyst, such as powdered copper or powdered copper bronze.
Gegenstand der Erfindung sind somit halogenierte Hexa-2,4-diene gemäß Patentanspruch 1 sowie die in den Patentansprüchen 2 und 3 gekennzeichneten Verfahren zu ihrer Herstellung.The invention therefore relates to halogenated hexa-2,4-dienes according to claim 1 and to the processes for their preparation characterized in claims 2 and 3.
Die erfindungsgemäßen Verbindungen selbst können dadurch hergestellt werden, daß man ein Keton der Formel °=c:40&udf54;&udf53;vu10&udf54;&udf53;vz3&udf54; &udf53;vu10&udf54;mit dem Ylid umsetzt, das durch Dehydrohalogenierung eines 3,3-Dimethylallyl-triphenylphosphonium-halogenids erhalten worden ist.The compounds according to the invention themselves can be prepared by reacting a ketone of the formula °=c:40&udf54;&udf53;vu10&udf54;&udf53;vz3&udf54;&udf53;vu10&udf54; with the ylide which has been obtained by dehydrohalogenation of a 3,3-dimethylallyl-triphenylphosphonium halide.
Ein anderes Verfahren zur Herstellung solcher erfindungsgemäßer Verbindungen, in denen einer der Reste R¹ und R² für Trifluoromethyl und der andere für Trifluoromethyl oder Difluoromethyl steht, besteht darin, daß man eine Verbindung der Formel °=c:60&udf54;&udf53;vu10&udf54;&udf53;vz5&udf54; &udf53;vu10&udf54;durch Behandlung mit Phosphorpentoxid dehydratisiert.Another process for preparing such compounds according to the invention in which one of the radicals R¹ and R² is trifluoromethyl and the other is trifluoromethyl or difluoromethyl consists in dehydrating a compound of the formula °=c:60&udf54;&udf53;vu10&udf54;&udf53;vz5&udf54;&udf53;vu10&udf54;by treatment with phosphorus pentoxide.
Die Erfindung wird durch die folgenden Beispiele näher erläutert.The invention is explained in more detail by the following examples.
Dieses Beispiel erläutert die Herstellung von 1-Chloro-1,1-difluoro-2-chlorodifluoromethyl-5-methylhexa-2,4-dien der Formel °=c:60&udf54;&udf53;vu10&udf54;&udf53;vz5&udf54; &udf53;vu10&udf54;This example illustrates the preparation of 1-chloro-1,1-difluoro-2-chlorodifluoromethyl-5-methylhexa-2,4-diene of the formula °=c:60&udf54;&udf53;vu10&udf54;&udf53;vz5&udf54;&udf53;vu10&udf54;
Ein Gemisch aus 50,0 g 3,3-Dimethylallyl-bromid, 88,0 g Triphenylphosphin und 500 ml trockenem Toluol wurde 1 h gerührt und unter Rückfluß erhitzt und dann 18 h auf Raumtemperatur gehalten. Die weiße Ausfällung von 3,3-Dimethylallyl-triphenylphosphonium-bromid (Fp. 242°C) wurde durch Filtration gesammelt, mit Diäthyläther gewaschen und getrocknet.A mixture of 50.0 g of 3,3-dimethylallyl bromide, 88.0 g of triphenylphosphine and 500 ml of dry toluene was stirred and refluxed for 1 h and then kept at room temperature for 18 h. The white precipitate of 3,3-dimethylallyl triphenylphosphonium bromide (m.p. 242°C) was collected by filtration, washed with diethyl ether and dried.
65,0 ml einer 15%igen (G/G) Lösung von n-Butyl-lithium in Hexan wurden langsam zu einer heftig gerührten Suspension von 65,0 g 3,3-Dimethylallyl-triphenylphosphonium-bromid in 500 ml trockenem Petroläther (Kp. 30 bis 40°C) bei 0°C unter einer Stickstoffatmosphäre gegeben, worauf das Gemisch 18 h lang auf Raumtemperatur gehalten wurde. Das Gemisch wurde dann auf 0°C abgekühlt, worauf 31,44 g 1,3-Dichlorotetrafluoroaceton zugegeben wurden. Das Gemisch wurde dann während eines Zeitraums von 2 h auf Raumtempratur erwärmen gelassen, worauf die Ausfällung abfiltriert wurde. Das Filtrat wurde durch Verdampfen konzentriert, bis das Volumen ungefähr 70 ml betrug, und durch eine kurze Aluminiumoxid-Kolonne hindurchgeführt, worauf das verbliebene Lösungsmittel unter atmosphärischem Druck bei einer Temperatur von 69°C abgedampft wurde. Die zurückbleibende Flüssigkeit wurde einer fraktionierten Destillation unterworfen, und die bei 79 bis 80°C/26,6 mbar siedende Fraktion wurde gesammelt und durch IR- und NMR-Spektroskopie als 1-Chloro-1,1-difluoro-2-2chlorodifluoromethyl-5-methyl-hexa-2,4-dien- identifiziert. NMR (CCl&sub4;) ppm 1,88 bis 1,94 (m, 6H); 6,3 (d, 1H); 7,08 (d, 1H).65.0 ml of a 15% (w/w) solution of n-butyl lithium in hexane was slowly added to a vigorously stirred suspension of 65.0 g of 3,3-dimethylallyl triphenylphosphonium bromide in 500 ml of dry petroleum ether (bp 30-40°C) at 0°C under a nitrogen atmosphere and the mixture was kept at room temperature for 18 hours. The mixture was then cooled to 0°C and 31.44 g of 1,3-dichlorotetrafluoroacetone was added. The mixture was then allowed to warm to room temperature over a period of 2 hours and the precipitate was filtered off. The filtrate was concentrated by evaporation until the volume was approximately 70 ml and passed through a short alumina column and the remaining solvent was evaporated under atmospheric pressure at a temperature of 69°C. The residual liquid was subjected to fractional distillation and the fraction boiling at 79-80°C/26.6 mbar was collected and identified by IR and NMR spectroscopy as 1-chloro-1,1-difluoro-2-2chlorodifluoromethyl-5-methyl-hexa-2,4-diene. NMR (CCl₄) ppm 1.88-1.94 (m, 6H); 6.3 (d, 1H); 7.08 (d, 1H).
