✦ Synopsis

The monofluorenyl zirconium complex [ ( ~+ ~' : 1 1 ~-fashion. The relatively weak fluorenyl-zirconium bond is C13H8C132CI120Me)ZrC12(p-Cl)]2, (2), has been obtained by stabilized by intramolecular coordination of the ether sidereaction of the respective fluorenyl lithium derivative with chain attached to the fluorenyl backbone. Despite this, the ZrCle in diethyl ether. A single-crystal X-ray structural analy-bidentate ligand is easily detached upon dissolution of 2 in sis shows that 2 is a chloride-bridged dimer, in which the THF. Simultaneous ether cleavage produces spiro[cycloprofluorenyl ligand is bonded in a transitional tri-to pentahapto pane-l,9'-fluorene].
