feedstock isoprene with unactivated silanes has been developed using earth‐abundant iron catalysts. The manipulation of regioselectivity relies on fine modification of the coordination geometry of the iron center. While a bidentate pyridine imine ligand promoted the formation of allylic silanes through 4,1‐addition, selectivity for the 3,4‐adduct homoallylic silanes was observed with a tridentate nitrogen
Group 6 anionic μ-hydride complexes catalyze hydrogenation of conjugated olefins, aldehydes, ketoesters, and alkynes, and hydrosilylation of aldehydes and conjugated olefins with high regio- and stereoselectivity. Ketones are converted into silyl ethers and silyl enol ethers with monohydrosilanes and dihydrosilanes, respectively.
