(R)-H8-BINAP

Description:
(R)-H8-BINAP, with the CAS number 139139-86-9, is a chiral bidentate ligand commonly used in asymmetric catalysis. It is derived from BINAP (1,2-bis(diphenylphosphino)ethane) and features a hydrogenated backbone, which enhances its solubility and stability in various solvents. This compound is characterized by its ability to form stable complexes with transition metals, particularly palladium and rhodium, facilitating enantioselective reactions. The presence of two phosphine groups allows for strong coordination to metal centers, making it effective in catalyzing reactions such as hydrogenation, cross-coupling, and other transformations that require chirality. The (R) configuration indicates its specific stereochemistry, which is crucial for achieving the desired enantiomeric excess in reactions. Additionally, (R)-H8-BINAP is valued for its relatively low toxicity and ease of handling, making it a popular choice in both academic and industrial settings for the synthesis of chiral compounds.
