产品介绍 |
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. |
