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.
