摘要：
The reaction of [Cp'2YMe](2) (Cp' = C5H5, C5H4SiMe3) with B(C6F5)(3) affords the complexes Cp'Y-2{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.
