摘要

Evidence of the involvement of a “cocktail”-type catalytic system in the alkyne and alkene hydrosilylation reaction in the presence of platinum on a carbon support is reported. The nature of the catalytic system was studied by employing a consistently developed experimental procedure. The existence of a “cocktail”-type catalysis pathway was shown for the hydrosilylation reaction catalyzed by platinum on multiwalled carbon nanotubes (Pt/MWCNT) and platinum on charcoal (Pt/C), with silane variation. The type of catalyst had a significant influence on the “cocktail”-type system formation. Involvement of a multichannel catalytic system requires critical rethinking of the principles of catalyst design. Another approach should be utilized to achieve high activity, stability and recycling compared to classical heterogeneous catalytic systems.
