Description

Verfahren zur Herstellung von Sulfonsäurederivaten y-Sulfonsäurederivate der a, a-Dihalogenbuttersäure bzw. ihrer Ester sind in der Literatur nicht bekannt.Process for the preparation of sulfonic acid derivatives γ-sulfonic acid derivatives α, α-dihalobutyric acid or its esters are not known in the literature.

Es wurde gefunden, daß man diese Verbindungen dadurch herstellen kann, daß man funktionelle Derivate der Dihalogenessigsäuren, z. B. Amide, Ester oder Nitrile, an a,ß-ungesättigte Sulfonsäuren oder deren funktionelle Derivate in Gegenwart von alkalischen Mitteln anlagert. It has been found that these compounds can be made in this way can that one functional derivatives of dihaloacetic acids, z. B. amides, esters or nitriles, α, β-unsaturated sulfonic acids or their functional derivatives accumulates in the presence of alkaline agents.

So erhält man z. B. aus Vinylsulfonsäureester und Dichloressigester in Gegenwart von Alkalialkoholaten a,a-Dichlor-y-alkoxysulfonylbuttersäureester. An Stelle der Vinylsulfonsäureester kann man auch Vinylsulfonsäureamide und substituierte Vinylsulfonsäurederivate verwenden. Der Dichloressigester ist bei dieser Reaktion z. B. durch Dichloracetonitril, Dibromessigester ersetzbar. Als alkalische Kondensationsmittel eignen sich in erster Linie Alkalialkoholate, z. B. Natriummethylat. Es genügen dabei schon katalytische Mengen; man kann aber, besonders bei niedrigen Reaktionstemperaturen, auch größere Alkalialkoholatmengen verwenden, ohne daß Nebenreaktionen stattfinden. Die Anlagerungsreaktion verläuft exotherm. Sie kann in Anwesenheit oder Abwesenheit eines Lösungs-oder Verdünnungsmittels, wie Benzol oder Toluol, durchgeführt werden. So you get z. B. from vinyl sulfonic acid ester and dichloroacetic ester in the presence of alkali alcoholates a, a-dichloro-y-alkoxysulfonylbutyric acid ester. Instead of vinyl sulfonic acid esters, vinyl sulfonic acid amides and substituted ones can also be used Use vinyl sulfonic acid derivatives. The dichloroacetic ester is involved in this reaction z. B. can be replaced by dichloroacetonitrile, dibromoacetate. As an alkaline condensing agent are primarily alkali metal alcoholates, e.g. B. sodium methylate. It is enough at the same time catalytic amounts; but you can, especially at low reaction temperatures, also use larger amounts of alkali metal alcoholate without side reactions taking place. The addition reaction is exothermic. It can be present or absent a solvent or diluent, such as benzene or toluene, can be carried out.

Es war nicht zu erwarten, daß die erfindungsgemäße Reaktion im beschriebenen Sinne verlaufen würde. Vielmehr war zu erwarten, daß Esterkondensationen oder Austausch von Halogen gegen Alkoxygruppen stattfinden würden. It was not to be expected that the reaction according to the invention in the described Senses would run. Rather, it was to be expected that ester condensations or exchanges of halogen versus alkoxy groups would take place.

Die Erzeugnisse des erfindungsgemäßen Verfahrens sind beständige Verbindungen; soweit sie nicht fest sind, lassen sie sich unzersetzt destillieren. The products of the process according to the invention are stable Links; if they are not solid, they can be distilled without decomposition.

Sie können als Ausgangsmaterialien für zahlreiche Synthesen, z. B. von Arzneimitteln und Pflanzenschutzmitteln, dienen.They can be used as starting materials for numerous syntheses, e.g. B. of pharmaceuticals and pesticides.

Beispiel 1 150 g Vinylsulfonsäurepropylester (1 Mol) wurden zusammen mit 143 g Dichloressigsäuremethylester (1 Mol) in 500ccm Toluol gelöst; zu der Lösung wurden unter Rühren langsam 6g festes Natriummethylat gegeben. Die exotherme Reaktion wurde durch Kühlung so geleitet, daß die Temperatur 40° C nicht überschritt. Nach mehrstündigem Rühren bei Zimmertemperatur wurde mit Äther versetzt und mit verdünnter Essigsäure neutral gewaschen. Example 1 150 g of propyl vinyl sulfonate (1 mole) were added together with 143 g of methyl dichloroacetate (1 mol) dissolved in 500ccm of toluene; to the solution 6 g of solid sodium methylate were slowly added with stirring. The exothermic reaction was passed through cooling so that the temperature did not exceed 40.degree. To stirring for several hours at room temperature was mixed with ether and diluted with Acetic acid washed neutral.

Nach Trocknen der organischen Phase über Natriumsulfat wurde destilliert Kp.o,os mm = 128 bis 1300 C, Ausbeute 220 g, entsprechend 750/0 der Theorie an y-Propoxysulfonyl- a,a- dichlorbuttersäuremethylester der Formel Beispiel 2 Eine Lösung von 163 g Vinylsulfonsäurediäthylamid und 143 g Dichloressigsäuremethylester in 500 ccm Toluol wurde, wie im vorstehenden Beispiel beschrieben, mit 6 g Natriummethylat versetzt. Die Aufarbeitung erfolgte ebenfalls wie im vorstehenden Beispiel. 220 g r-Diäthylamidosulfonyl-a,a-dichlorbuttersäuremethylester, Kp.l = 154 bis 1550 C und F. = 37° C, der Formel wurden erhalten.After the organic phase had been dried over sodium sulfate, it was distilled, boiling point os mm = 128 to 1300 ° C., yield 220 g, corresponding to 750/0 of theory, of methyl y-propoxysulfonyl-a, a-dichlorobutyrate of the formula EXAMPLE 2 A solution of 163 g of vinylsulphonic acid diethylamide and 143 g of methyl dichloroacetate in 500 cc of toluene was admixed with 6 g of sodium methylate as described in the above example. Work-up was also carried out as in the previous example. 220 g of methyl r-diethylamidosulfonyl-a, a-dichlorobutyrate, boiling point = 154 to 1550 ° C. and melting point = 37 ° C., of the formula were received.

Analog erhält man den y-Morpholidosulfonyla,a-dichlorbuttersäuremethylester, F. = 910 C, in 71 Obiger Ausbeute. The y-morpholidosulfonyla, a-dichlorobutyric acid methyl ester, is obtained analogously, F. = 910 C, in 71 above yield.

Beispiel 3 Eine Lösung von 163 g Vinylsulfonsäurediäthylamid und 110 g Dichloracetonitril in 500 ccm Toluol wurde, wie oben beschrieben, mit 6 g Natriummethylat versetzt und aufgearbeitet. Man erhielt 190 g y-Diäthylamidosulfonyl-a, a-dichlor butyronitril, Kp.0,3 mm = 1280 C. Example 3 A solution of 163 g of vinylsulfonic acid diethylamide and 110 g of dichloroacetonitrile in 500 ccm of toluene was, as described above, with 6 g Sodium methylate is added and worked up. Man received 190 g of γ-diethylamidosulfonyl-a, a-dichlorobutyronitrile, bp 0.3 mm = 1280 C.
