Reaction Steps

252 mg Styrene, 91 mg 1,1,3,3-tetramethyldisiloxane, and 64 mg toluene were placed in a nitrogen-purged glass tube. This was followed by the addition of 0.005 mL ethyltriacetoxysilane and 0.002 mL of a toluene solution (platinum content=0.4 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 60° C. After cooling, GC analysis of the product showed the following: the 1,1,3,3-tetramethyldisiloxane had been consumed; the styrene:1,1,3,3-tetramethyldisiloxane 2:1 adduct had been produced in a yield of 93%; and the α,α-adduct:α,β-adduct:β,β-adduct ratio was 1:4.3:6.3.
