実験手順

Added dropwise at 5° C., under argon, to 3-mercaptopropyldimethylethoxysilane (34.0 g, 0.191 mol) in solution in triethylamine (19.2 g, 0.191 mol) and cyclohexane (400 ml) is octanoyl chloride (31.0 g, 0.191 mol) over 15 minutes at 8° C. The reaction medium is stirred for 15 hours at ambient temperature. The precipitate of triethylamine hydrochloride Et3N.HCl is filtered. The mixture obtained is purified by flash chromatography (eluent: petroleum ether, 500-600 ml). After evaporating the solvents under reduced pressure at 24° C., the S-octanoylmercaptopropylethoxydimethylsilane E with CAS number [1024594-66-8] (45.0 g, 0.148 mol) is obtained in the form of a colourless liquid with a yield of 78%.
