Regioselective 1-Hexene Oligomerization Using Cationic Bis(phenolato) Group 4 Metal Catalysts: Switch from 1,2- to 2,1-Insertion

Regioselective 1-Hexene Oligomerization Using Cationic Bis(phenolato) Group 4 Metal Catalysts: Switch from 1,2- to 2,1-Insertion

A cat of two tales: Cationic Group 4 metal catalysts that contain a linked bis(phenolato) ligand efficiently catalyze the oligomerization of 1‐hexene. Whereas oligo(1‐hexene)s arising from 2,1‐insertion of 1‐hexene are observed for the titanium complexes, those prepared using zirconium and hafnium c...

Zusammenfassung:A cat of two tales: Cationic Group 4 metal catalysts that contain a linked bis(phenolato) ligand efficiently catalyze the oligomerization of 1‐hexene. Whereas oligo(1‐hexene)s arising from 2,1‐insertion of 1‐hexene are observed for the titanium complexes, those prepared using zirconium and hafnium complexes are formed by 1,2‐insertion.
