Syntheses and characterization of mono(6,6-dimethylcyclohexadienyl) complexes of titanium and zirconium

Abstract Reactions of appropriate bis(6,6-dmch) (dmch = dimethylcyclohexadienyl) complexes of titanium(II) or zirconium(IV) with dichloroethane or phosphines, respectively, have led to loss of one dienyl ligand, and the formation of mono(6,6-dmch) complexes of Ti(III) or Zr(IV). The polymeric [Ti(6,6-dmch)Cl 2 ] n and Zr(6,6-dmch)Br 3 (dmpe) (dmpe = 1,2-bis(dimethylphosphino)ethane) have thus been isolated, and fully characterized.
