Abstract

Restoring order: YIII, EuIII, and ErIII tris(ligand) complexes of a new chiral alkoxide ligand, tBu2P(O)CH2CH(tBu)OH (HL), preferentially form as C3‐symmetric diastereomers. Thus racemic HL affords (RRR)‐ and (SSS)‐[LnL3] complexes, which are active catalysts for the stereoselective polymerization of rac‐lactide to afford highly isotactic polylactic acid.
