Umsetzung nach dem Verfahren der Erfindung ist es nicht unbedingt erforderlich, die Dimethyloxosulfurylene der Formel II aus deren Herstellungsgemisch abzutrennen. Als Ausgangsstoffe kann man z. B. Dimethyloxosulfurylenacetanilid, Dimethyloxosulfurylenacettoluidid, Dimethyloxosulfurylenessigsäuremethylamid, Dimethyloxosulfurylenaceton, Dimethyloxosulfurylenacetophenon und Dimethyloxosulfurylen-N-phenyläthylacetamid verwenden.Implementation according to the process of the invention, it is not absolutely necessary to use the dimethyloxosulfurylenes of the formula II to be separated from their preparation mixture. As starting materials you can z. B. Dimethyloxosulfurylenacetanilid, Dimethyloxosulfurylenacettoluidid, Dimethyloxosulfurylenessigsäuremethylamid, Dimethyloxosulfurylenaceton, Dimethyloxosulfurylenacetophenon and dimethyloxosulfurylene-N-phenylethylacetamide use.

Als ungesättigte Nitrile kann man z. B. Acrylsäurenitril, Methacrylsäurenitril, Crotonsäurenitril, Maleinsäure- oder Fumarsäurenitril verwenden.As unsaturated nitriles you can, for. B. Acrylic acid nitrile, methacrylic acid nitrile, crotonic acid nitrile, maleic acid or use fumaric acid nitrile.

Unter niedermolekularen Alkanolen der Formel R4OH sind solche zu verstehen, deren Rest R4 1 bis 8 Kohlenstoffatome enthält. Bevorzugt verwendet man unverzweigte Alkanole.Low molecular weight alkanols of the formula R 4 OH are to be understood in which the radical R contains from 4 1 to 8 carbon atoms. Unbranched alkanols are preferably used.

Das Verfahren läßt sich ohne Lösungsmittel durchführen. Man kann aber auch in Gegenwart von Lösungsmitteln arbeiten. Als Lösungsmittel eignen sich Kohlenwasserstoffe, wie Hexan, Heptan, Cyclohexan oder Benzol, ferner Äther, wie Diäthyläther oder Dibutyläther, N,N-disubstituierte Carbonsäureamide, wie Dimethylformamid oder N-Methylpyrrolidon. Schließlich kann man auch in Gegenwart von überschüssigem Alkohol arbeiten. Der Alkohol ist dabei gleichzeitig Reaktionsteilnehmer und Lösungsmittel. The process can be carried out without a solvent. But you can also do it in the presence of Solvents work. Hydrocarbons such as hexane, heptane and cyclohexane are suitable solvents or benzene, also ethers, such as diethyl ether or dibutyl ether, N, N-disubstituted carboxamides, such as dimethylformamide or N-methylpyrrolidone. After all, you can also do it in the present work from excess alcohol. The alcohol is both a reactant and a solvent.

1 Mol Dimethyloxosulfurylen reagiert mit 2 Mol Nitril und l'Molcdes Alkanols. Es ist jedoch zweckmäßig, das Nitril und das Alkanol in einem überschuß anzuwenden, z. B. je Mol Dimethyloxosulfurylen 3 bis 20 Mol Nitril und 10 bis 100 Mol Alkanole. Zur Abtrennung der gewünschten Verfahrensprodukte kann man die leicht flüchtigen Bestandteile aus dem Umsetzungsgemisch abdestillieren und den Rückstand Umkristallisieren.1 mole of dimethyloxosulfurylene reacts with 2 moles of nitrile and l'Molcdes alkanol. However, it is useful to apply the nitrile and the alkanol in excess, e.g. B. per mole of dimethyloxosulfurylene 3 to 20 moles of nitrile and 10 to 100 moles of alkanols. For the separation of the desired process products the volatile constituents can be distilled off from the reaction mixture and the residue Recrystallize.

Die nach dem Verfahren der Erfindung herstellbaren Verbindungen sind wertvolle Ausgangsstoffe für die Herstellung von Arzneimitteln und Pflanzenschutzmitteln. Außerdem können die Dinitrile zu bifunktionellen Säuren oder Aminen umgewandelt werden, die sich zu Kunststoffen verarbeiten lassen.The compounds which can be prepared by the process of the invention are valuable starting materials for the manufacture of pharmaceuticals and pesticides. In addition, the dinitrile can too bifunctional acids or amines, which can be processed into plastics.

Beispielexample

4,22 Teile Dimethyloxosulfurylenacetanilid, 40 Teile frisch destilliertes Acrylsäurenitril und 40 Teile Methanol werden 45 Minuten unter Rückfluß erhitzt. Die leicht flüchtigen Bestandteile werden abdestilliert. Der Rückstand wird in 200 Teilen Benzol aufgenommen. Man wäscht mit 300 Teilen Wasser in drei Portionen, engt den Benzolextrakt ein und löst aus Cyclohexan und Essigester um. Man erhält 2,02 Teile kristallines y-Methoxy-y-carbanilido-a, ω-dicyanopentan vom F. = 820C, Die Ausbeute beträgt 40% der Theorie, bezogen auf angewandtes Dimethyloxosulfuryjenacetanilid. 4.22 parts of dimethyloxosulfurylene acetanilide, 40 parts of freshly distilled acrylonitrile and 40 parts of methanol are refluxed for 45 minutes. The volatile constituents are distilled off. The residue is taken up in 200 parts of benzene. It is washed with 300 parts of water in three portions, the benzene extract is concentrated and dissolved in cyclohexane and ethyl acetate. This gives 2.02 parts of crystalline y-methoxy-y-carbanilido-a, ω-dicyanopentane, mp = 82 0 C, The yield is 40% of theory, based on applied Dimethyloxosulfuryjenacetanilid.
