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 carbon-silicon bond in alkenyl(alkoxy)silanes is readily cleaved by hydrogen peroxide to form the corresponding aldehydes, carboxylic acids or ketones, depending upon the nature of the alkenyl group and the reaction conditions.

PCcarbeneP pincercomplex (1) was reacted with a range of alkynes to generate complexes 2a–e and 4a–f featuring a bidentate η3-benzophosphorine–phosphino ligand PC3R1,R2(P)}. As such, a variety of electronic and steric components could be incorporated into the PC3R1,R2(P) ligand at a late synthetic stage. These complexes were found to be competent catalysts for the hydrosilylation of alkynes, providing
