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.
