Abstract

Abstract New C s-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.
