Advantageously one uses the Dimethyloxosulfurylen in a deficiency. This ensures that the implementation is quantitative with regard to the valuable dimethyloxosulfurylenes.

Zur Abtrennung der gewünschten Verfahrensprodukte destilliert man im allgemeinen das Lösungsmittel und den überschüssigen Reaktionsteilnehmer 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 reactant. From the residue you can then get the pure ones Substances e.g. B. win by distillation or recrystallization. But you can also the process products by adding another solvent, z.
