Reaction Steps

280 mg Vinyltrimethoxysilane and 381 mg 1,1,3,3-tetramethyldisiloxane were placed in a nitrogen-purged glass tube. This was followed by the addition of 28 mg dimethylacetoxysilane and 0.005 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 1 hour in an oil bath at 80° C. After cooling, GC analysis of the product showed the following: the vinyltrimethoxysilane had been consumed; the vinyltrimethoxysilane:1,1,3,3-tetramethyldisiloxane 1:1 adduct had been produced in a yield of 71%; and the α-adduct:β-adduct ratio was 1:5.7.
