Ferner kann man als Lösungsmittel auch Alkanole mit niederer Kohlenstoffzahl verwenden, wie Methanol, Äthanol oder Butanol.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, Ν, Ν-disubstituted carboxamides, such as dimethylformamide or N-methylpyrrolidone. Alkanols can also be used as solvents Use with a lower carbon number such as methanol, ethanol or butanol.
Die Umsetzungsteilnehmer können in stöchiometrischer Menge angewandt werden. Vorteilhafterweise verwendet man die Dimethyloxosulfurylene in einem Unterschuß. Dadurch wird erreicht, daß die Umsetzung im Hinblick auf die wertvollen Dimethyloxosulfurylene quantitativ ist.The reaction participants can be used in a stoichiometric amount. Advantageously one uses the Dimethyloxosulfurylen in a deficiency. This ensures that the Implementation in terms of the valuable Dimethyloxosulfurylenes is quantitative.

Zur Abtrennung der gewünschten Verfahrensprodukte destilliert man im allgemeinen das Lösungsmittel und den überschüssigen Umsetzungsteilnehmer ab. Aus dem Rückstand kann man dann die reinen Stoffe, z. B. durch Destillation oder Umkristallisieren, gewinnen. Man kann aber auch die Verfahrensprodukte durch Zugabe eines weiteren Lösungsmittels, z. B. Wasser, aus dem Umsetzungsgemisch ausfällen und dann abtrennen.To separate off the desired process products, the solvent is generally distilled off and the excess implementation participants. From the residue you can then get the pure ones Substances, e.g. B. by distillation or recrystallization, win. But you can also use the process products by adding another solvent, e.g. B. water, precipitate from the reaction mixture and then detach.
Die nach dem Verfahren der Erfindung herstellbaren Stoffe sind wertvolle Zwischenprodukte für die Herstellung von Arznei- und Schädlingsbekämpfungsmitteln. The substances which can be prepared by the process of the invention are valuable intermediates for Manufacture of medicines and pesticides.

4,22 Teile Dimethyloxosulfurylen-acetanilid, 5 Teile Methyljodid und 500 Teile Methanol werden 100 Stunden bei 20° C gehalten. Das Methanol wird unter ver- ao mindertem Druck abdestilliert (20°C/10Torr). Der Rückstand wird aus mit Wasser verdünntem Methanol kristallisiert. Man erhält 2,15 Teile «-Jodpropionanilid vom F. = 131° C. Die Ausbeute beträgt 39% der Theorie, bezogen auf angewandtes Dimethyloxosulfurylen-acetanilid. 4.22 parts of dimethyloxosulfurylene acetanilide, 5 parts of methyl iodide and 500 parts of methanol are 100 hours held at 20 ° C. The methanol is distilled off under reduced pressure (20 ° C./10 Torr). Of the The residue is crystallized from methanol diluted with water. 2.15 parts of α-iodopropionic anilide are obtained from the F. = 131 ° C. The yield is 39% of theory, based on the dimethyloxosulfurylene acetanilide used.
44 Teile Trimethyloxosulfoniumjodid und 5,34 Teile 90%iges Natriumhydrid werden in 400 Teilen Di- 3u methylsulfoxyd gelöst.
