ASYMMETRIC CATALYSTS PREPARED FROM OPTICALLY ACTIVE BISPHOSPHITES BRIDGED BY ACHIRAL DIOLS

摘要

This invention relates to asymmetric hydroformylation (hf) processes in which a prochiral or chiral compound is contacted in the presence of an optically active metal-ligand complex catalyst to produce an optically active aldehyde or product derived from an optically active aldehyde. The invention encompasses novel ligands and catalysts for use in such processes.
