Notes:
The monofluorenyl zirconium complex [(.(5):.1-C13H8CH2CH2OMe)ZrCl2(μ-Cl)]2, (2), has been obtained bby reaction of the respective fluorenyl lithium derivative with ZrCl4 in diethyl ether. A single-crystal X-ray structural analysis shows that 2 is a chloride-bridged dimer, in which the fluorenyl ligand is bonded in a transitional tri- to pentahapto fashion. The relatively weak fluorenyl-zirconium bond is stabilized by intramolecular coordination of the ether sidechain attached to the fluorenyl backbone. Despite this, the bidentate ligand is easily detached upon dissolution of 2 in THF. Simultaneous ether cleavage produces spiro[cyclopropane-1,9′-fluorene].
