Alternate tacticities : The ring‐opening polymerization of rac ‐β‐butyrolactone ( rac ‐BBL) using a six‐coordinate yttrium complex bearing a dianionic amine‐bis(phenolate) ligand as initiator proceeds readily at room temperature to give the corresponding poly(3‐hydroxybutyrate) (PHB) with up to 94 % syndiotacticity and narrow molecular‐weight distributions (see scheme).
