Abstract
B(C6F5)(3) reacts with the fulvene complex 5):sigma-eta(1)-tetramethyl fulvene)phenylzirconium (CpFvZrPh) (I) selectively under attack at th e 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. (C) 1997 Elsevier Science S .A.
