摘要：

Reaction of the cation Cp2ZrMe(p-MeB(C6F5)(3)) or Cp(tBu(3)PN)TiMe(mu-MeB(C6F5)(3))with (RC5H4)(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 cyctopentadienyl ligand.
