Reaction Conditions

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 10 mg acetic acid and 0.009 mL of a toluene solution (platinum content=0.04 weight %) of a zero-valent platinum complexed with divinylsiloxane. The reaction 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: the triethoxysilane and 1,1,3,3-tetramethyldisiloxane had been almost entirely consumed (>98%); the styrene:1,1,3,3-tetramethyldisiloxane 2:1 adduct had been produced in a yield of 96%; the styrene:triethoxysilane 1:1 adduct had been produced in a yield of 97%; the α,β-adduct:β,β-adduct ratio for the former was 1:19; and the α-adduct:β-adduct ratio for the latter was 1:185.
