(R)-(-)-N,N-Dimethyl-1-[(S)-2-(diphenylphosphino)ferrocenyl]ethylamine丨CAS 55700-44-2

(R)-(-)-N,N-Dimethyl-1-[(S)-2-(diphenylphosphino)ferrocenyl]ethylamine, commonly referred to as a chiral ferrocene-based phosphine ligand, is widely used in asymmetric catalysis and organometallic chemistry. Its primary application is in transition-metal-catalyzed asymmetric reactions, such as hydrogenation, allylic substitution, and cross-coupling, where it enables the synthesis of optically active compounds with high enantioselectivity. It is extensively employed in pharmaceutical and fine chemical synthesis to produce enantiomerically pure intermediates and active pharmaceutical ingredients. The ferrocenyl backbone provides rigidity and electronic tunability, while the diphenylphosphino group allows strong coordination with metals such as rhodium, ruthenium, and palladium, enhancing both reactivity and stereocontrol in catalytic systems.

The benefits of this chiral ferrocene phosphine ligand arise from its unique combination of axial chirality, steric bulk, and electron-rich phosphine functionality. The ferrocenyl moiety provides a rigid and electronically tunable scaffold, which allows precise control over the geometry around the metal center, resulting in high enantioselectivity in asymmetric reactions. Its N,N-dimethylamino substituent enhances solubility and fine-tunes electronic properties, while the diphenylphosphino group ensures strong and stable coordination with transition metals. These features collectively improve catalytic efficiency, selectivity, and reaction rates, making it highly valuable in the synthesis of optically active compounds, particularly in pharmaceutical and fine chemical applications. Its versatility also allows modification and adaptation for different metal-catalyzed transformations.
