Abstract

Graphical abstract: Highlights: Asymmetric synthesis using bimetallic chiral nanoparticles (BMCNP) as catalysts. Focused on BMCNP catalysts Rh/Co, Cu/Fe, Pd/Fe, Rh/Ag, Pd/Au, and Pt/Fe. Pauson–Khand reaction, Suzuki–Miyaura coupling, 1, 4-additon, reduction, hydrosilylation, and allylation reactions. Abstract: Chiral nanoparticles have become one of the most versatile catalyst for the effective construction of chiral organic moieties. Recently, bimetallic nanoparticles as catalysts have gained interest among the chemists. The presence of hetero metal–metal interactions has modified the surface of the catalyst both electronically and geometrically to show unique activities, selectivities and possess an improved stability than the corresponding monometallic catalyst. In this review, the newly emerging bimetallic chiral nanoparticle catalysts (Rh/Co, Cu/Fe, Pd/Fe, Pt/Fe, Pd/Au, Rh/Ag, etc.) and their application in asymmetric Pauson–Khand reactions, hydrosilylation, Suzuki–Miyaura coupling, α-arylation of tetralones, reduction of ketones, allylation of nitrobenzaldehyde, 1, 4-additon reactions and arylation of aldimines have been discussed.
