Ligand Synthesis

Monomer/dimer zirconium complexes 4–6 were synthesized by changing the molar ratio of ZrCl4 : ligand. The catalytic behaviors of these zirconium complexes were investigated in the presence of MAO as a cocatalys.

The title complexes have been characterized for X = F by multinuclear NMR (including [1H,19F]-HMBC) experiments, confirming that the observed 19F–1H (and –13C) coupling occurs with chemical connectivity across C–H⋯F–C interactions, and their catalytic efficiencies for ethylene polymerization have been investigated.
