英文摘要	The amine elimination reaction of quinolinyl aminophenol (LH2) with Ln[N(SiMe3)(2)](3)(mu-Cl)Li(THF)(3) in THF afforded lanthanide-lithium aminophenoxy complexes L(2)LnLi(THF)(2) (Ln = Yb (1), Sm (2)), while the similar reaction with Ln[N(SiMe3)(2)](3) in toluene gave normal monoamido lanthanide complexes LLnN(SiMe3)(2)(DME) (Ln = Sm (3), Nd (4), La (5)). All complexes have been fully characterized. X-ray structural determination revealed that complexes 1 and 2 have a monomeric C-2-symmetric hetero-bimetallic structure, in which the lanthanide atom is connected to the lithium atom by two oxygen bridges from two phenoxy(quinolinyl) amide ligands. Complexes 4 and 5 have a solvated monomeric structure, and the lanthanide metal centers adopt a distorted octahedral geometry. It was found that complexes 3-5 initiated the ring-opening polymerization of 1,4-dioxan-2-one (PDO) with high activity. (C) 2014 Elsevier B.V. All rights reserved.
