(4R,5R)-(-)-2,2-Dimethyl-4,5-bis((diphenylphosphino)methyl)-1,3-dioxolane is a chiral bis-phosphine ligand (CAS: 109687-84-3) essential for asymmetric catalysis. Synthesized via condensation of chiral diols with diphenylphosphinomethyl chloride, it features high optical purity (>98%) to ensure stereoselectivity in metal complexes.
Store under inert atmosphere at -20°C to prevent oxidation. Use in fume hoods due to potential phosphine toxicity; avoid contact with skin and eyes requiring appropriate PPE.
