Effect of cocatalysts on the character of a constrained geometry catalyst

Abstract
A constrained geometry catalyst (CGC) precursor, Me2Si(Flu)(N‐t‐Bu)ZrX2 (X = Cl or NMe2), behaved as a single site catalyst with methylaluminoxane (MAO) as cocatalyst, while it developed much diversified catalytic species with AIR3/Ph3CB(C6F5)4 as cocatalyst. The catalytic performance was not affected if X is Cl or NMe2.
