Visible light accelerated hydrosilylation of alkynes using platinum-[acyclic diaminocarbene] photocatalysts

Platinum-[diaminocarbene] complexes work as transition-metal photocatalysts for the hydrosilylation of alkynes. A catalytic system operates under visible light irradiation (blue LED) enabling the conversion of a range of terminal and internal alkynes to respective vinyl silanes in excellent yields.
