  Stereoselective synthesis and structural characterization of rac-planar chiral bis(2-methoxyethylindenyl)lanthanum and yttrium tetrahydroborates

  摘要：

  Racemic planar chiral metallocenes bis(2-methoxyethylindenyl) yttrium and lanthanum tetrahydroborates (MeOCH2CH2C9H6)(2)Ln(mu(2)-H)(n)BH4-n (Ln = Y, n = 2 (1); Ln = La, n = 3, (2)) have been stereoselectively isolated in high yield by reaction of the corresponding lanthanocene chlorides with sodium borohydride in THF at room temperature. The two complexes have been fully characterized by elemental analyses, MS, H-1 NMR and IR spectra. The tetrahydroborate ion has been identified as slipped bidentate (mu(2)-H)(2)BH2 and tridentate (mu(2)-H)(3)BH ligands in 1 and 2, respectively. (C) 2000 Elsevier Science Ltd. All rights reserved.

  Chiral lanthanocene complexes with an ether-functionalized indene ligand: synthesis and structure of bis{1-(2-methoxyethyl)indenyl}lanthanocene chlorides

  摘要：

  Chiral lanthanocene chlorides (CH3OCH2CH2C9H6)(2)LnCl (Ln = Y 1, La 2, Nd 3, Gd 4, Ho 5 and Lu 6) with an ether-functionalized indenyl ligand were synthesized by the reaction of 1-(2-methoxyethylindenyl) potassium (in situ) with corresponding anhydrous lanthanide chlorides in THF. The X-ray crystal structures of four such complexes were determined and these indicated that they were unsolvated monomeric complexes with a trans arrangement of both the sidearms and indenyl rings in the solid state. This configuration also predominated in THF solution, as evidenced by NMR spectra of the diamagnetic complexes 1, 2 and 6, although some minor species of 1 and 2 did form upon dissolution.
