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.

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.

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.
