Die Stoffe gemäß vorliegender Erfindung stellen somit eine echte Bereicherung der Technik dar.Surprisingly, the aryl-N-alkyl-carbamates according to the invention have a better insecticidal action than the carbamates of analogous constitution and the same direction of action known from the literature.

Die als Ausgangsstoffe zu verwendenden Aryl-N-alkyl-carbamate (II) sind bekannt oder können nach bekannten Verfahren leicht hergestellt werden (vergleiche Deutsche Auslegeschrift 1 254 617 und Belgische Patentschrift 746 649). Als Beispiele dafür seien im einzelnen genannt:

  • 2-methylthiomethylphenyl, 2-ethylthiomethylphenyl, 2-n-propylthiomethylphenyl and 2-iso-propylthiomethylphenyl, 2-n-butylthiomethylphenyl, 2-iso-butylthiomethylphenyl and 2 -sec.-Butylthiomethyl-phenyl-N-methyl- or -N-ethyl-, -Nn-propyl-, -N-iso-propyl-, -Nn-butyl-, -N-iso-butyl- and -N sec-butyl carbamate.

Die weiterhin als Ausgangsstcffe zu verwendenden Sulfenylhalogenide (III) sind ebenfalls bekannt oder nach bekannten Verfahren herstellbar (vergleiche Belgische Patentschriften 817 515 und 817 517). Als Beispiele dafür seien im einzelnen genannt:

  • Dimethylamino-, Diäthylamino-, Di-n-propylamino-, Di-isopropylamino-, Pyrrolidinyl(1), Piperidyl (1) und Morpholinyl(4)-sulfenylchlorid.
The sulfenyl halides (III) which are also to be used as starting materials are also known or can be prepared by known processes (see Belgian patents 817 515 and 817 517). The following are examples of this:
  • Dimethylamino, diethylamino, di-n-propylamino, di-isopropylamino, pyrrolidinyl (1), piperidyl (1) and morpholinyl (4) sulfenyl chloride.

Das Verfahren zur Herstellung der erfindungsgemäßen Verbindungen wird bevorzugt unter Mitverwendung geeigneter Lösungs-oder Verdünnungsmittel durchgeführt. Als solche kommen praktisch alle inerten organischen Solventien infrage. Hierzu gehören insbesondere aliphatische und aromatische, gegebenenfalls chlorierte Kohlenwasserstoffe, wie Benzol, Toluol, Xylol, Benzin, Methylenchlorid, Chloroform, Tetrachlorkohlenstoff, Chlorbenzol, oder Äther, z.B. Diäthyl- und Dibutyl- äther, Dioxan, ferner Ketone, beispielsweise Aceton, Methyl- äthyl-, Methylisopropyl- und Methylisobutylketon, außerdem Nitrile, wie Aceto- und Propionitril oder Pyridin.The process for the preparation of the compounds according to the invention is preferably carried out using suitable solvents or diluents. Practically all inert organic solvents can be considered as such. These include in particular aliphatic and aromatic, given if chlorinated hydrocarbons, such as benzene, toluene, xylene, gasoline, methylene chloride, chloroform, carbon tetrachloride, chlorobenzene or ether, for example diethyl and dibutyl ether, dioxane, and also ketones, for example acetone, methyl ethyl, methyl isopropyl and methyl isobutyl ketone, also nitriles, such as aceto- and propionitrile or pyridine.

Als Säureakzeptoren können alle üblichen Säurebindemittel Verwendung finden. Besonders bewährt haben sich Alkalicarbonate und -alkoholate, wie Natrium- und Kaliumcarbonat, Natrium- und Kaliummethylat bzw. -äthylat, ferner aliphatische, aromatische oder heterocyclische Amine, beispielsweise Triäthylamin, Trimethylamin, Dimethylanilin, Dimethylbenzylamin und Pyridin.All customary acid binders can be used as acid acceptors. Alkali carbonates and alcoholates, such as sodium and potassium carbonate, sodium and potassium methylate or ethylate, and also aliphatic, aromatic or heterocyclic amines, for example triethylamine, trimethylamine, dimethylaniline, dimethylbenzylamine and pyridine, have proven particularly useful.

Die Reaktionstemperatur kann innerhalb eines größeren Bereichs variiert werden. Im allgemeinen arbeitet man zwischen 0 und 80°C, vorzugsweise bei lo bis 35°C.The reaction temperature can be varied within a wide range. In general, one works between 0 and 8 0 ° C, preferably at lo to 35 ° C.

Die Umsetzung läßt man im allgemeinen bei Normaldruck ablaufen.The reaction is generally allowed to proceed at normal pressure.

Zur Durchführung des Verfahrens setzt man die Ausgangskomponenten meist in äquivalentem Verhältnis ein. Ein Überschuß der einen oder anderen Reaktionskomponente bringt keine wesentlichen Vorteile. Die Reaktionskomponenten werden meist in einem der oben angeführten Lösungsmittel zusammengegeben und meist bei Raumtemperatur zur Vervollständigung der Reaktion mehrere Stunden gerührt. Danach gibt man die Reaktionsmischung auf ein Gemisch aus Eis/Säure und nimmt das sich ausscheidende Öl in einem organischen Lösungsmittel, z.B. Toluol, auf. Die organische Phase wird wie üblich durch Waschen, Trocknen und Abdestillieren des Lösungsmittels aufgearbeitet.To carry out the process, the starting components are usually used in an equivalent ratio. An excess of one or the other reaction component has no significant advantages. The reaction components are usually combined in one of the solvents listed above and are usually stirred for several hours at room temperature to complete the reaction. The reaction mixture is then poured onto an ice / acid mixture and the oil which separates out is taken up in an organic solvent, e.g. Toluene. As usual, the organic phase is worked up by washing, drying and distilling off the solvent.

Die neuen Verbindungen fallen in Form von ölen an, die sich zum Teil nicht unzersetzt destillieren lassen, jedoch durch sogenanntes "Andestillieren", d.h. durch längeres Erhitzen unter vermindertem Druck auf mäßig erhöhte Temperaturen von den letzten flüchtigen Anteilen befreit und auf diese Weise gereinigt werden. Zu ihrer Charakterisierung dient der Brechungsindex.The new compounds are obtained in the form of oils, some of which cannot be distilled without decomposing, but by so-called "distillation", i.e. can be freed from the last volatile constituents by prolonged heating under reduced pressure to moderately elevated temperatures and can be cleaned in this way. The refractive index is used to characterize them.
