The photoactivated (350 nm) hydrosilylation of alkynes by silanes catalyzed by platinum(II) bis(acetylacetonato) has been studied. Platinum(II) bis(acetylacetonato) is an efficient catalyst. High yields of adducts (>98% for terminal alkynes) can be obtained in 2–3 h after a short induction period with a catalyst–reactant molar ratio of 10−3/1. The reaction rate depends on the choice of silane, irradiation

Rhodium(III) and iridium(III) complexes of Tröger's base (TB), of structural type TB·2MCl3 (M = Rh, Ir), were prepared by treatment of TB with MCl3. The rhodium complex readily catalyzed the hydrosilylation of alkynes with high regio- and stereoselectively observed in some cases.

Platinumnanoparticles 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
