Stereo-electronic contributions in yttrium-mediated stereoselective ring-opening polymerization of functional racemic β-lactones: ROP of 4-alkoxymethylene-β-propiolactones with bulky exocyclic chains
Résumé
ROP of bulky functional β-lactones mediated by an achiral diamino-bis(phenolate) yttrium catalyst affords syndio-enriched polyhydroxyalkanoates.
