Highly effective functionalization of monovinylsiloxy heptaisobutylsilsesquioxane and octavinylspherosilicate of the formula (ViMe 2 SiO)( i Bu) 7 Si 8 O 12 ( 1 ) and (ViMe 2 SiO) 8 Si 8 O 12 ( 2 ), respectively, with a variety of olefins, by using a Ru(H)(Cl)(CO)(PCy 3 ) 2 ‐catalyzed silylative coupling procedure is reported. The cross‐metathesis reaction catalyzed by a ruthenium–carbene complex does not proceed for this system. Whereas the reaction of 1 and 2 with styrene takes place highly stereo‐ and regioselectively, the respective reaction with 1‐hexene gives a mixture of isomers. However, functionalization of 1 and 2 with vinylic heteroatom‐substituted (N, O, Si) derivatives was found to be highly efficient for the synthesis of spherosilicates with β‐heteroatom vinylic functionalities (© Wiley‐VCH Verlag GmbH & Co.
