Use	2,2 ′-bis (diphenylphosphine)-1,1 ′-binaphthalene and its rhodium and ruthenium derivatives can be used as highly selective homogeneous catalysts for the reduction of aryl ketones, β-keto esters and α-amino ketones. It can also be used for asymmetric hydrogenation and hydroformylation of olefins, asymmetric Heck reaction and asymmetric isomerization of allyl groups. Ligands for palladium-catalyzed asymmetric tandem Heck reactions, this carbanion capture process allows the synthesis of tricyclic sesquiterpene. It can also be used for ruthenium-catalyzed asymmetric hydrogenation of α,β-unsaturated acids.
