  Verfahren zur Herstellung von Thiophosphorsäureestern
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von   Thiophosphorsäureestem    der Formel
EMI1.1     
 in welcher R für niedere Alkylreste und X für Schwefel oder Sauerstoff stehen, das dadurch gekennzeichnet ist, dass O,   O-Dialkyl-thio-bzw.-dithio-    phosphorsäuresalze mit Propargylhalogeniden umgesetzt werden. Geeignete Salze sind beispielsweise die Alkalisalze, besonders jedoch die leicht zugänglichen Ammoniumsalze der obengenannten Säuren.



   Ferner betrifft die Erfindung die Verwendung der neuen Thiophosphorsäureester zur   Schädlings-    bekämpfung.



   Die erfindungsgemäss erhaltenen neuen Verbindungen zeichnen sich durch eine gute   Spinnmilben-    und Blattläuse-Wirkung aus und besitzen zum Teil systemische Eigenschaften. Sie werden in der für andere Phosphorsäureester üblichen Art und Weise angewandt, das heisst bevorzugt als Komponente in Schädlingsbekämpfungsmitteln, welche die üblichen festen oder flüssigen Streck-bzw.   Verdünnungsmit-    tel enthalten. Feste Streckmittel sind z. B. Talkum, Kreide, Bentonit, Tonerde, Kaolin usw. Als flüssiges Verdünnungsmittel kommt vor allem Wasser in Frage, worin die obengenannten Verbindungen zweckmässig unter Verwendung eines   Hilfslosemittels,    wie Dimethylformamid oder Aceton, und eines han  delsüblichen    Emulgators einemulgiert werden.



  Beispiel 1
EMI1.2     

51 g des Ammoniumsalzes der   0,      0-Diäthyl-di-    thiophosphorsäure werden in 150 cm3   Methyläthyl-    keton gelöst. Bei   800 werden    19   g Propargylchlorid    zugetropft. Die Temperatur wird   1    Stunde beibehalten, wobei die Reaktion unter ständigem Rühren beendet wird. Nach Absaugen vom gebildeten Ammoniumchlorid wird das Lösemittel abdestilliert, der Rückstand in Ather aufgenommen und die   äthe-    rische Schicht zweimal mit je 50 cm3 Wasser gewaschen. Nach dem Trocknen der ätherischen Schicht mit Natriumsulfat wird der Ather abdestilliert und der Rückstand im Hochvakuum rektifiziert.



  Der Ester siedet bei 0,1 mm bei 66 . Die Ausbeute beträgt 41 g =   73 ouzo    der Theorie.



   Beispiel 2
EMI1.3     

41 g des Ammoniumsalzes der 0,   0-Diäthyl-thiol-    phosphorsäure werden in 125   cm3    Athanol gelöst.



  Bei   700 werden    sodann 20 g Propargylchlorid zugegeben. Unter beständigem Rühren wird bei der gleichen Temperatur innerhalb einer Stunde die Re aktion vervollständigt. Es wird wie im Beispiel 1 angegeben aufgearbeitet, wobei 25 g   =    49 /o der Theorie des neuen Esters der obenangegebenen Formel erhalten werden. Der Ester siedet bei 0,01 mm bei   55 .    Blattläuse und Spinnmilben werden von 0,1 /oigen Lösungen 100 /aig abgetötet.



     PATENTANSPRtYCHE   
I. Verfahren zur Herstellung von   Thiophosphor-    säureestern der Formel
EMI2.1     
 worin   R    für niedere Alkylreste und X für Schwefel oder Sauerstoff stehen, dadurch gekennzeichnet, dass   0, 0-Dialkyl-thio-bzw.-dithiophosphorsäuresalze    mit   Propargylhalogeniden    umgesetzt werden.



  



  Process for the preparation of thiophosphoric acid esters
The present invention relates to a process for the preparation of thiophosphoric acid esters of the formula
EMI1.1
 in which R stands for lower alkyl radicals and X stands for sulfur or oxygen, which is characterized in that O, O-dialkyl-thio- or -dithiophosphoric acid salts are reacted with propargyl halides. Suitable salts are, for example, the alkali metal salts, but especially the easily accessible ammonium salts of the abovementioned acids.



   The invention also relates to the use of the new thiophosphoric acid esters for pest control.



   The new compounds obtained according to the invention are distinguished by a good action of spider mites and aphids and some of them have systemic properties. They are used in the manner customary for other phosphoric acid esters, that is to say preferably as a component in pesticides which contain the customary solid or liquid extenders or. Contains thinner. Solid extenders are e.g. B. talc, chalk, bentonite, clay, kaolin, etc. As a liquid diluent, especially water comes into question, in which the above compounds are conveniently emulsified using an auxiliary such as dimethylformamide or acetone, and a commercial emulsifier.



  example 1
EMI1.2

51 g of the ammonium salt of 0, 0-diethyl-di- thiophosphoric acid are dissolved in 150 cm3 of methyl ethyl ketone. At 800, 19 g of propargyl chloride are added dropwise. The temperature is maintained for 1 hour, the reaction being terminated with constant stirring. After the ammonium chloride formed has been filtered off with suction, the solvent is distilled off, the residue is taken up in ether and the ethereal layer is washed twice with 50 cm3 of water each time. After the ethereal layer has been dried with sodium sulfate, the ether is distilled off and the residue is rectified in a high vacuum.



  The ester boils at 0.1 mm at 66. The yield is 41 g = 73 ouzo of theory.



   Example 2
EMI1.3

41 g of the ammonium salt of 0, 0-diethyl-thiol-phosphoric acid are dissolved in 125 cm3 of ethanol.



  At 700, 20 g of propargyl chloride are then added. With constant stirring, the reaction is completed within one hour at the same temperature. It is worked up as indicated in Example 1, with 25 g = 49 / o of the theory of the new ester of the formula given above. The ester boils at 55 at 0.01 mm. Aphids and spider mites are killed by 0.1% solutions of 100%.
