Abstract

Complexes of rhenocene (Cp₂Re) with substitution at the cyclopentadienyl rings have been prepared from Cp₂Re−Me by dilithitation of the Cp rings followed by reaction with Me₂SiCl₂ or Cl(SiMe₂)₂Cl to afford ansa-bridged species. Protonation of the resulting neutral Re methyl complexes gives thermally labile methyl hydride complexes. The thermal stability of the methyl hydride complex with a single silicon atom in the ansa bridge is enhanced with respect to the unbridged analogues.
