(R)-(-)-[(S)-2-(Diphenylphosphino(ferrocenyl]ethyldi-t-butylphosphine

Description:
The chemical substance known as (R)-(-)-[(S)-2-(Diphenylphosphino(ferrocenyl]ethyldi-t-butylphosphine, with CAS number 155830-69-6, is a chiral phosphine ligand commonly used in asymmetric synthesis and catalysis. This compound features a ferrocenyl moiety, which contributes to its unique electronic properties and stability, making it valuable in various catalytic applications, particularly in transition metal complexes. The presence of bulky t-butyl groups enhances steric hindrance, which can influence the selectivity and reactivity of the ligand in catalytic processes. The diphenylphosphino group provides strong coordination capabilities to transition metals, facilitating the formation of stable complexes. As a chiral ligand, it can induce asymmetry in reactions, making it useful in the synthesis of enantiomerically enriched compounds. Its structural characteristics, including chirality and steric bulk, play a crucial role in its effectiveness in catalysis, particularly in reactions such as hydrogenation and cross-coupling. Overall, this compound exemplifies the importance of ligand design in achieving specific reactivity and selectivity in chemical transformations.
