Reaction Steps

928 mg Styrene, 426 mg 1,1,3,3-tetramethyldisiloxane, and 348 mg triethoxysilane were placed in a nitrogen-purged glass tube. This was followed by the addition of 0.009 mL of a toluene solution (platinum content=0.04 weight %) of a zero-valent platinum complexed with divinylsiloxane. The tube was then sealed with Teflon® tape and a rubber septum and heated for 2 hours in an oil bath at 80° C. After cooling, GC analysis of the product showed the following: 84% of the 1,1,3,3-tetramethyldisiloxane had been consumed; 31% of the triethoxysilane had been consumed; the styrene:1,1,3,3-tetramethyldisiloxane 2:1 adduct had been produced in a yield of 51%; the styrene: triethoxysilane 1:1 adduct had been produced in a yield of 28%; the α,α-adduct:α,β-adduct:β,β-adduct ratio for the former was 1:6.5:13.9; and the α-adduct:β-adduct ratio for the latter was 1:6.
