Abstract

Abiotic attempts to mimic certain advantageous enzyme characteristics have recently focused on construction of multimetallic catalytic centers capable of achieving cooperative recognition/activation/reactivity effects between proximate transition-metal ions.[1] Regarding such effects in singlesite polymerization catalysis,[2–4] we recently reported that a constrained geometry binuclear catalyst and binuclear cocatalyst combination (C2-Zr2+ ...
