Abstract:
Here, we report a highly efficient rhodium-catalysed enantioselective hydrosilylation of unactivated alkenes, achieving excellent regioselectivity and high enantioselectivity. The use of a commercially available chiral ferrocene-based phosphine-oxazoline ligand was crucial in achieving excellent chiral induction and high reactivity with undirected unactiviated alkenes, delivering Si-stereogenic monohydrosilanes in high yields and excellent enantioselectivities. This protocol represents a robust, scalable method for the enantioselective synthesis of Si-stereogenic monohydrosilanes, featuring a low catalyst loading, a broad substrate scope and exceptional functional group and heterocycle tolerance. Moreover, the late-stage functionalization of complex motifs opens a new avenue for incorporating chiral silicon motifs into pharmaceuticals and bioactive compounds.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
