Kinetic resolution of racemic α-olefins with ansa-zirconocene polymerization catalysts: Enantiomorphic site vs. chain end control

Copolymerization of racemic α-olefins with ethylene and propylene was carried out in the presence of enantiopure C(1)-symmetric ansa metallocene, {1,2-(SiMe(2))(2)(η(5)-C(5)H-3,5-(CHMe(2))(2))(η(5)-C(5)H(3))}ZrCl(2) to probe the effect of the polymer chain end on enantioselection for the R- or S-α-o...
