  Syntheses and reactivities of bisaryloxo lanthanide chlorides and crystal structures of [Ln(ArO)2Cl(THF)2]·(MePh) (Ln=Er, Yb) and [Sm(ArO)2(THF)3]·(MePh) (ArO=2,6-di-tert-butyl-4-methylphenoxo)

  摘要：

  Four bisaryloxo lanthanide chlorides Ln(ArO)(2)Cl(THF)(2) (Ln = Sm (1), Er (2), Yb (3), Y (4)) (ArO = 2,6-di-tert-butyl-4-methylphenoxo) were synthesized by the reaction of anhydrous LnCl(3) with 2 equiv. of NaOAr in THF at room temperature in high yield. These chlorides can be used as starting materials to synthesize heteroleptic lanthanide aryloxides. Complex 3 reacted with 1 equiv. of MeCpNa in THF to form a complex (MeCp)Yb(ArO)(2)(THF) (5) containing mixed ligands. The divalent aryloxo lanthanide complexes Sm(ArO)(2)(THF)(3) (6) and Yb(ArO)(2)(THF)(3) (7) were obtained in good yield by reducing compounds 1 and 3 with sodium metal in THF, respectively. Single crystal structures of complexes 2-PhMe, 3-PhMe and 6-PhMe were determined. Complexes 2 and 3 are isostructural, in which one chlorine atom, two aryloxo ligands and two THF molecules are coordinated to the central metal to form a distorted trigonal bipyramid geometry. Complex 6 has similar stereochemistry to that of 2 and 3. (C) 2001 Published by Elsevier Science Ltd.
