Flexibly Tethered Dinuclear Zinc Complexes: A Solution to the Entropy Problem in CO2/Epoxide Copolymerization Catalysis?
Working in zinc: Kinetic investigations of a new zinc catalyst (see scheme) for the copolymerization of CO2 and epoxides show a reversible shift in the rate‐determining step from epoxide ring opening to CO2 insertion, depending on the applied pressure. This shift is attributed to the similarity of t...

| description | Working in zinc: Kinetic investigations of a new zinc catalyst (see scheme) for the copolymerization of CO2 and epoxides show a reversible shift in the rate‐determining step from epoxide ring opening to CO2 insertion, depending on the applied pressure. This shift is attributed to the similarity of the activation barriers and explains the exceptionally high activities for the copolymerization. |
