Achiral Lanthanide Alkyl Complexes Bearing N,O Multidentate Ligands. Synthesis and Catalysis of Highly Heteroselective Ring-Opening Polymerization of rac-Lactide

Alkane elimination reactions of amino-amino-bis(phenols) H 2 L 1 - 4, Salan H 2 L 5, and methoxy-β-diimines HL 6,7 with lanthanide tris(alkyl)s, Ln(CH 2 SiMe 3 ) 3 (THF) 2 (Ln = Y, Lu), respectively, afforded a series of lanthanide alkyl complexes 1 − 8 with the release of tetramethylsilane.
