| 英文摘要 | Treatment of yttrium tris(alkyl)s, Y(CH2SiMe3)(3)(THF)(2), by equimolar H(C5Me4)SiMe3(HCp') and indene (Ind-H) afforded (eta(5)-Cp')Y(CH2SiMe3)(2)(THF) (1) and (eta(5)-Ind)Y(CH2SiMe3)(2)(THF) (2) via alkane elimination, respectively. Complex 1 reacted with methoxyamino phenols, 4,6-(CH3)(2)-2-[(MeOCH2CH2)(2)-NCH2]-C6H2-OH (HL1) and 4,6-(CMe3)(2)-2-[(MeOCH2CH2)(2)-NCH2]-C6H2OH (HL2) gave mixed ligands supported alkyl complexes [(eta(5)-Cp')(L)]Y(CH2SiMe3) (3: L = L-1; 4: L = L-2). Whilst, complex 2 was treated with HL2 to yield [(eta(5)-Ind)(L-2)]Y(CH2SiMe3) (5). The molecular structures of 3 and 5 were confirmed by X-ray diffraction to be mono(alkyl)s of THF-free, adopting pyramidal and tetragonal-bipyramidal geometry, respectively. Complexes 3 and 5 were high active initiators for the ring-opening polymerization Of L-lactide to give isotactic polylactide with high molecular weight and narrow to moderate polydispersity.
