Application: Useful ligand for transition metal catalyzed asymmetric reactions, including hydrogenation and disilylation. 2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl and its rhodium and ruthenium derivatives are highly selective homogeneous catalysts used for the reduction of aryl ketones, β-keto esters, and α-amino ketones. They have also been used for asymmetric hydrogenation and hydroformylation of olefins, asymmetric Heck reactions, and asymmetric isomerizations of allyls.^9,
Complex with Ag(I) used to catalyze an asymmetric aldol reaction between alkenyl trichloroacetates and aldehydes. Also used with Ag(I) to catalyze an enantioselective hetero-Diels-Alder reaction of azo compounds.

Packaging: 250 mg in glass bottle
