Platinum nanoparticles were stabilized at the surface of carbon nanotubes and the nanohybrid was valorized as a catalyst for the hydrosilylation of alkenes and alkynes. The heterogeneous catalyst operated under sustainable conditions (room temperature, no solvent, low catalyst loading, air atmosphere) and exhibited improved stabilty as recycling and reuse could be achieved for multiple consecutive reactions.

The catalytic activity of the pentamethylcyclopentadienylsilicon(II) cation Cp*Si:+ was investigated. It was shown that Cp*Si:+ efficiently catalyzes reactions of technical relevance in organosilicon chemistry: Cp*Si:+ proved to be a very efficient nonmetallic catalyst for the hydrosilylation of olefins at low catalyst amounts of 0.01 mol % and for the Piers-Rubinsztajn reaction in order to make controlled silicone topologies. The thermal induction of hydrosilylation which is important for the manufacturing of silicone rubber can be achieved by small amounts of alkoxysilanes.

Bis(dialkylamino)carbenium salts {[(Me2N)2CCl]+}2MCl4 2- (M = Ni, Pd) and {[Me2NC(X)NR2]+}2PtCl62- (R = Me, All; X = H, Cl, Me) are efficient catalysts for hydrosilylation of allyl phenyl ether, triallylamine, allyl chloride, allylamine, and 1-octene with various hydrosilanes. The catalytic activity is dependent on the salt composition and the nature of the metal M, the saturated compound, and the hydrosilane used. The catalysts used are usually insoluble in the reaction mixture, active, and stable. In some cases, carbenium salts are more selective than Speier's catalyst. Novel catalysts, silica-immobilized dialkylaminocarbenium salts, have been prepared. The kinetics of the reaction have been considered.
