| 英文摘要 | Mesomeric divalent 1,1'-(3-oxapentamethylene)-bridged bis(indenyl)lanthanidocenes, meso-[O(CH2CH2C9H6)(2)]Ln(.)(DME) (Ln = Sm (2),Yb (3)), have been synthesized by reduction of a mixture of rac/meso-[O(CH2CH2C9H6)(2)]LnCl(.)THF (Ln = Sm, Yb) with Na or reaction of LnI(2) (Ln = Sm, Yb) with [O(CH2CH2C9H6K)(2)] in THF followed by recrystallization in DME. The structures of these meso, ansa-lanthanidocenes were determined by X-ray diffraction analysis. The factors that dictated the rac/meso selectivity are discussed. Nonbridged divalent lanthanide complexes (CH3OCH2CH2C9H6)(2)Ln(II) (Ln = Sm (4), Yb (5)) were also synthesized for comparison by the reaction of LnI(2) (Ln = Sm, Yb) with (CH3OCH2CH2C9H6)(2)K in THE Stereoselective polymerization of methyl methacrylate with these divalent lanthanide complexes as single-component catalysts was preliminarily investigated. |
