Overview

This product and its derivatives, rhodium and ruthenium 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. Ligand used in a palladium-catalyzed, asymmetric, tandem Heck reaction-carbanion capture process leading to a synthesis of a tricyclic sesquiterpene. Also used in a ruthenium-catalyzed asymmetric hydrogenation of α,β-unsaturated acids.
Reactant involved in : Enantioselective and diastereoselective unpoled carbonyl allylation;Syntehsis of organophophine oxides as anittumor agents;SN2 halogenation of hydroxy groups;Synthesis of BINAP complexes and Studies of conformational flexibility of BINAP chelates
