A series of Group 4 metal complexes bearing new phenoxy(benzimidazolyl)-imine, -amine and -amide ligands has been synthesized. Derivatives containing benzyl ligands undergo benzyl migration and an unusual C–C coupling process to afford binuclear species in which the metals are linked by a central pi...
