Procedure

362 mg Vinyltrimethoxysilane and 362 mg tris(dimethylsiloxy)-n-propylsilane were placed in a nitrogen-purged glass tube. This was followed by the addition of 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 on an oil bath at 80° C. After cooling, GC analysis of the product showed the following: the starting materials had been entirely consumed; the vinyltrimethoxysilane:tris(dimethylsiloxy)-n-propylsilane 1:1 adduct, 2:1 adduct, and 3:1 adduct were produced at 1:4.9:3.4 as the GC (FID) area ratio; and the α-hydrosilylation:β-hydrosilylation ratio in these products was 1:2.4.
