Preparation of a hafnocene–ethylene complex from bis(η5-cyclopentadienyl)hafnacyclopentane and its characterization
Abstract
Addition of PMe3 to zircona– and hafna–cyclopentane derivatives afforded the corresponding zirconocene– and hafnocene–ethylene complexes, respectively, by C–C bond fission, the latter being the first example of hafnocene–alkene complexes.
