Synthesis of bis-cyclopentadienyl compounds with a 9,9-fluorenylidene bridge. Crystal and molecular structure of [μ-9,9-Flu(η5-Cp)2]ZrCl2

Article abstract of DOI:10.1007/BF02495776

An efficient synthetic approach to 9,9-bis(cyclopentadienyl)fluorenes was developed. The two corresponding ansa-zirconocenes were synthesized. The structure of one of these compounds was established by X-ray diffraction analysis.
