Description
Verfahren zur Herstellung von Thiophosphorsäureestern 0,0-Dialkylthio- bzw. -dithiophosphorsäureester, in denen der am Schwefel befindliche Esterrest ein Acylphenylrest, z. B. der Acetophenylrest, ist, sind bisher aus der Literatur nicht bekannt.Process for the preparation of thiophosphoric acid esters 0,0-dialkylthio- or -dithiophosphoric acid esters, in which the ester residue located on the sulfur is a Acylphenyl radical, e.g. B. the acetophenyl radical, are not yet from the literature known.
Es wurde gefunden, daß man zu dieser Gruppe sehr wirksamer Thiophosphor- bzw. Dithiophosphorsäureester gelangen kann, wenn man entsprechende Acylphenylmercaptomethylhalegenide mit Salzen von 0,0-Dialkylthio- bzw. -dithiophosphorsäureestern umsetzt. Diese Umsetzung wird bevorzugt bei Raumtemperatur bzw. leicht erhöhter Temperatur und in Gegenwart inerter Lösungs- bzw. Verdünnungsmittel durchgeführt.It has been found that this group of very effective thiophosphorus or dithiophosphoric acid ester can arrive if one uses corresponding acylphenylmercaptomethylhalegenide with salts of 0,0-dialkylthio- or dithiophosphoric acid esters. This implementation is preferred at room temperature or slightly elevated temperature and in the presence inert solvent or diluent carried out.
Die Anwendung der neuen Verbindungen geschieht in prinzipiell bekannter Weise, nämlich in Kombination mit festen oder flüssigen Streck- oder Verdünnungsmitteln. Als solche Streckmittel haben sich vor allem Kreide, Talkum, Bentonite und Kieselgur bewährt. Falls flüssige Kombinationen angewandt werden sollen, bestehen diese vorzugsweise aus wäßrigen Emulsionen, die unter Mitverwendung geeigneter Lösungshilfsmittel und handelsüblicher Emulgatoren leicht aus den vorstehenden Verbindungen hergestellt werden können.The new compounds are used in a manner that is known in principle Way, namely in combination with solid or liquid extenders or diluents. Chalk, talc, bentonite and kieselguhr have proven to be the most common such extenders proven. If liquid combinations are to be used, these preferably exist from aqueous emulsions, with the use of suitable solubilizers and commercially available emulsifiers are easily made from the above compounds can be.
Gegenüber den aus der deutschen Patentschrift 957 213 bekannten Thiophosphorsäureestem zeichnen sich die erfindungsgemäß erhältlichen Verbindungen durch eine bessere Wirksamkeit gegen Fliegenmaden bei gleichzeitig geringerer Toxizität gegen Warmblüter aus, wie aus der nachfolgenden Tabelle ersichtlich ist.Compared to the thiophosphoric acid esters known from German patent specification 957 213 the compounds obtainable according to the invention are distinguished by a better effectiveness against fly maggots with lower toxicity against warm-blooded animals, such as can be seen in the table below.

Beispiel 2 Dieser neue Ester wird erhalten, wenn man 60g 0,0-diäthylthionothiolphosphorsaures Ammonium in Aceton mit 41 g Chlormethyl-p-acetophenyl-sulfid (F. = 64°C) in Aceton analog dem Beispiel l umsetzt und wie dort angegeben aufarbeitet.Spider mites are killed with 0.011) / 1) iger solution 1001) / 1) ig. Example 2 This new ester is obtained if 60 g of ammonium 0,0-diethylthionothiolphosphoric acid are reacted in acetone with 41 g of chloromethyl-p-acetophenyl sulfide (mp = 64 ° C.) in acetone analogously to Example 1 and worked up as indicated there.

Beispiel 3 LäBt man 44 g 0,0-dimethylthionothiolphosphorsaures Ammonium mit 40 g Chlormethyl-p-acetophenyl-sulfid (F. = 64°C) nach der im Beispiel 1 erläuterten Methode reagieren, so erhält man nach der dort angegebenen Aufarbeitung 55 g des neuen Esters (entsprechend 85 % der Theorie) in Form eines hellgelben Öles.Yield: 70 g, corresponding to 99% of theory. Toxicity: rat per os DL "250 mg / kg. Spider mites are safely killed with 0.01% / yg solutions. Example 3 If 44 g of ammonium 0,0-dimethylthionothiolphosphoric acid are allowed to react with 40 g of chloromethyl-p-acetophenyl sulfide (mp = 64 ° C.) by the method explained in Example 1, 55 g of the new ester are obtained after the work-up indicated there (corresponding to 85 % of theory) in the form of a light yellow oil.
