Abstract

A constrained geometry catalyst (CGC) precursor, Me~2~Si(Flu)(N‐t‐Bu)ZrX~2~ (X = Cl or NMe~2~), behaved as a single site catalyst with methylaluminoxane (MAO) as cocatalyst, while it developed much diversified catalytic species with AIR~3~/Ph~3~CB(C~6~F~5~)~4~ as cocatalyst. The catalytic performance was not affected if X is Cl or NMe~2~.
