Versuchsvorschrift

This compound was made by first heating a mixture of 2.8 g (0.011 mol) of 3-{4-[2-(2-ethoxyethoxy)ethoxy]phenyl}-1 -propene (prepared as in Example 1), 5 g of benzene and 1.1 equivalent of methyldiethoxysilane under an argon atmosphere at 85° C. for one hour. After one hour, a trace amount (0.01 μL) of 1 part chloroplatinic acid in 1 part ethanol and 98 parts THF was added and the mixture was heated overnight at 85° C. The product was isolated by distillation to give 4.2 g (97%) of methyl diethoxy 3-{4-[2-(2-ethoxyethoxy)ethoxy]phenyl}propysilane, bp 135° C./0.08mm; NMR (δ): 0.20(3H,s), 0.65(2H,m), 1.05(9H,t), 1.50(2H,m), 2.70(2H,t), 3.90(12H,m), 7.0(2H,d), 7.15(2H,d).
