From THF to Furan:  Activity Tuning and Mechanistic Insight via Sidearm Donor Replacement in Group IV Amine Bis(phenolate) Polymerization Catalysts

Weakening the sidearm donor of amine bis(phenolate) titanium and zirconium polymerization catalysts causes a 10-fold enhancement in activity of the former and no difference in activity of the latter, while increasing the termination to propagation ratios in both.
