Stabilizing Zr and Ti cations by interaction with a ferrocenyl fragment.
Reaction of the cation Cp(2)ZrMe(mu-MeB(C(6)F(5))(3)) or Cp(tBu(3)PN)TiMe(mu-MeB(C(6)F(5))(3)) with (RC(5)H(4))(2)Fe (R = H, Me) yields remarkably stable, yet reactive cations. The early metal centers are stabilized by dative donation from Fe and an agostic interaction with a CH bond of an Fe-bound cyclopentadienyl ligand.
