Abstract:
Claimed is a process for producing a phosphorus-containing ligand, preferably a diphosphite ligand structure (DLS) such as structure I. The method includes contacting a phosphorochloridite (structure II) with a compound having the structure X—OH (which can be a bisaryl compound), and a tertiary organic amine to provide structure I′ and as preferred embodiment structure I.
