  A new chromium(III) complex, bearing a bis-thioether-diphenolate [OSSO]-type ligand, was found to be an efficient catalyst in the copolymerization of CO2 and epoxides to achieve poly(propylene carbonate), poly(cyclohexene carbonate), poly(hexene carbonate) and poly(styrene carbonate), as well as poly(propylene carbonate)(cyclohexene carbonate) and poly(propylene carbonate)(hexene carbonate) terpolymers

Complex 6 crystallized as homochiral dimer of pseudo-octahedral fragments with bridging μ2-alkoxide ligands, but in solution two diastereomers were observed. The isopropoxy complexes efficiently initiated the ring-opening polymerization of l-lactide in toluene

  The old switcheroo! The ring‐opening polymerization activity towards meso‐lactide significantly differs when cerium complexes with two bis(phenolate) ligands (OSSO type) change their oxidation state from +4 to +3. This switch can be performed in situ by chemical reduction or oxidation of the catalyst. The redox switching is possible up to three times in a row. PLA=polylactide.

  旧的switcheroo！当带有两个双酚盐配体的铈络合物（OSSO型）的铈络合物的氧化态从+4变为+3时，对内消旋丙交酯的开环聚合活性会显着不同。该转换可以通过催化剂的化学还原或氧化原位进行。连续最多可以进行三次氧化还原切换。PLA =聚丙交酯。
