Descripción general

Product Introduction

(R)-(+)-2,2′-Bis(diphenylphosphino)-1,1′-binaphthalene is an axially dissymmetric bis(triaryl)phosphine ligand for asymmetric reactions. 

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.

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.
