  ansa-Chromocenes: An alternative route to Me2Si(C5Me4)2Cr

  摘要：

  The mechanism for the preparation of Me2Si(C5Me4)(2)Cr, 1, from CrCl2(THF)(x) and Me2Si(C5Me4)(2)Li-2 was investigated and-in contrast to earlier claims-no evidence was found for the participation of an auxiliary ligand. The formation and stability of 1 is attributed to the combination of correct reaction conditions and a highly substituted ligand framework. Reactions with other ligands under identical conditions did not lead to the formation of ansa-chromocenes. Reaction with H(4)C(2)Ind(2)Li(2) afforded the eta(3)-Ind bridged dimer {H4C2(eta(5)-Ind)(mu-, eta(3)-Ind)Cr}(2), 9. Complex 1 does not coordinate PPh3 or carbenes, but from reaction with two equivalents of xylyl isocyanide the CH-activated complex Me2Si(C5Me4)(eta(C5Me4)-C-3(eta(3)- H)(H)(=CH2)Cr(CNC6MeH3)(2), 7, was obtained. Complexes 7 and 9 were characterised by X-ray crystallography. (C) 2010 Elsevier B. V. All rights reserved.
