Intramolecular sigma-Bond Metathesis / Protonolysis on ZrIV and HfIV Pyridyl-Amido Olefin Polymerization Catalyst Precursors: Exploring Unexpected Reactivity Paths

A temperature-controlled metathesis/protonolysis takes place on group 4 amidopyridinate polymerization catalyst precursors. Unraveling this unprecedented reactivity path allowed us to highlight the importance of the metal precursor choice while preparing improved catalytic structures or studying new catalytic processes.
