Analysis with chiral nuclear magnetic resonance shift reagents revealed that the isotactic poly (1,4-ketone) products were formed with an average or overall degree of enantioselectivity that was >90%. Using the same catalyst, Jiang and Sen also described the first example of alternating co-polymerization between an internal alkene (2-butene) and carbon monoxide to form an isotactic, optically active poly(l,5-ketone).
