CAS 76189-56-5 Usage

2,2′-bis(diphenylphosphine)-1,1′-binaphthalene and its rhodium and ruthenium derivatives can be used as highly selective homogeneous catalysts for aryl ketones, β-keto esters and Reduction of α-amino ketone.
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 reaction. This carbanion trapping process can synthesize tricyclic sesquiterpenes.
It can also be used for the asymmetric hydrogenation of α,β-unsaturated acid catalyzed by ruthenium.
