Cationic benzyl zirconium heteroscorpionates: synthesis and characterization of a novel ethylene polymerisation catalyst showing an unusual temperature dependent polymerisation mechanism.
The reaction of (bpzmp)Zr(CH2Ph)3 with B(C6F5)3 produces the active ethylene polymerisation catalyst [(bpzmp)Zr(CH2Ph)2]+[PhCH2B(C6F5)3]- which showed a temperature dependent polymerisation mechanism identified by variable temperature 1H NMR analysis of the catalyst solution.
