NovelCs-Symmetric 1,4-Diphosphine Ligands in the Copolymerization of Propene and Carbon Monoxide: High Regio- and Stereocontrol in the Catalytic Performance

Abstract

New Cs-symmetric aryl 1,4-diphosphine ligands were synthesized and tested in the copolymerization of carbon monoxide and propene. The electronic properties of the two different P-atoms did not affect the high enantioselectivity of the catalyst precursors, thus resulting in high ‘regio’- and ‘stereoregular’ copolymers.
