Abstract The reactions of separate and competitive hydrosilylation of propylene with HSiCl 3, MeSiHCl 2, Me 2 SiHCl, and MePh 2 SiH in the presence of the Speier catalyst (SC) with different additives and a catalyst obtained from SC and propylene were studied. A mutual influence of the hydrosilanes in the competitive reactions was found. The influence of various additives to SC on the process was considered.
