B(C6F5)3 reacts with the fulvene complex (pentamethylcyclopentadienyl)(π-η5: σ-η1-tetramethylfulvene)phenylzirconium (Cp * FvZrPh) (I) selectively under attack at the fulvene-CH2 group to form the highly sensitive zwitterionic complex (Cp * ){(C5Me4CH2-B(C6F5)3}ZrPh (II). Mixtures of I with either B(C6F5)3 or [CPh3][B(C6F5)4] are highly active for the polymerisation of ethene over a wide range of temperatures.
