The reaction of [Cp‘₂YMe]₂ (Cp‘ = C₅H₅, C₅H₄SiMe₃) with B(C₆F₅)₃ affords the complexes Cp‘₂Y{MeB(C₆F₅)₃}. The anion is coordinated in a chelating fashion via one ortho-fluorine atom and agostic interactions to two of the methyl hydrogens; the complexes are highly fluxional in solution. They act as initiators for the carbocationic polymerization of isobutene.
