With a view to addressing the shortcomings of traditional catalysts, a new generation of outstanding N‐ heterocyclic carbene platinum(0) complexes for the hydrosilylation of unsaturated carbon–carbon bonds is reported. Their discovery and application to the stereoselective addition of various silanes to silylated alkynes, terminalacetylenes, and olefins is presented. Insights into the catalytic cycle

The regioselectivehydrosilylation of terminal and internalalkynes catalyzed by the novel (IPr)Pt(AE) (7) (IPr = bis(2,6-diisopropylphenyl)imidazo-2-ylidene, AE = allyl ether) complex is presented. The (IPr)Pt(AE) catalyst displays enhanced activity and regioselectivity for the hydrosilylation of terminal and internalalkynes with low catalyst loading (0.1 to 0.05 mol %) when compared to the parent
