Potent ligands for transition metal-catalyzed asymmetric reactions including hydrogenation and disilylation. 2,2′-Bis(diphenylphosphine)-1,1′-binaphthyl and its rhodium and ruthenium derivatives can be used as highly selective homogeneous catalysts for aryl ketones, β-ketoesters and α- Reduction of aminoketones. It can also be used for asymmetric hydrogenation of alkenes Chemicalbook and hydroformylation, asymmetric Heck reaction and asymmetric isomerization of allyl groups. Its Ag(I) complex can be used to catalyze the asymmetric aldol reaction between alkenyl trichloroacetate and aldehyde. Its Ag(I) complex can also be used to catalyze the asymmetric heterogeneous Diels-Alder reaction of azo compounds.
