BISPHOSPHITE LIGANDS FOR CARBONYLATION PROCESSES

Title:

BISPHOSPHITE LIGANDS FOR CARBONYLATION PROCESSES

Document Type and Number:

WIPO Patent Application WO2003078444

Kind Code:

A3

Abstract:

A novel organophosphorus composition and synthesis thereof, the composition being characterized by one phosphite moiety, one phosoxophite moiety, and a plurality of sterically bulky substituents. The novel composition finds utility as a ligand in Group VIII transition metal phosoxophite complex catalysts and complex catalyst precursors that are used in carbonylation processes, preferably, hydroformylation processes. Additionally, there is disclosed a novel method of preparing a phosphoromonochloridite composition that finds utility as a precursor to the novel phosoxophite composition.
