Application

(S)-PPhos serves as a highly effective chiral dipyridylphosphine ligand specifically designed for use in asymmetric hydrogenation and Pd-catalyzed reactions. This white solid ligand is instrumental in the asymmetric hydrogenation of various substrates, including β-keto esters, 2-arylacrylates, aryl ketones, and α-dehydroamino acids, as well as the Pd-catalyzed asymmetric bis-alkoxycarbonylation of styrene. By facilitating these reactions, (S)-PPhos plays a crucial role in the production of chiral compounds, which are valuable in numerous chemical and pharmaceutical applications.
