Synthesis and spectroscopic characterization of group 4 post-metallocenes bearing (σ-aryl)-2-phenolate-6-pyridyl and -isoquinolinyl auxiliaries
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.
