Versuchsvorschrift

In a four-necked flask of 1 L, 18.0 g of 3-mercaptopropyl dimethoxymethyl silane and 11.1 g of triethylamine are dissolved in 300 mL of toluene under a nitrogen atmosphere. To this solution is added 16.2 g of octanoic acid chloride dropwise over 30 minutes, which is stirred for 2 hours. Thereafter, the precipitates are filtered off and the solvent is removed by a rotary evaporator at 20 hPa/40° C. to obtain 29.0 g of 3-octanoylthio-propyl dimethoxymethyl silane.
