Versuchsvorschrift

To 25 mL of dichlorodimethylsilane in a 100 mL r.b. flask was added 10 g of isethionic acid sodium salt and the mixture was heated to reflux with stirring for 20 hrs. The excess dichlorodimethylsilane was distilled and the residue transferred to a short-path distillation tube with a CH2Cl2 rinse. The residue was distilled at 145-175° C., 0.2 mm pressure, to give 8.25 g (67%) of a viscous liquid.
