Groups 2 and 3 metal complexes incorporating fluorenyl ligands

The panorama of fluorenyl complexes of alkaline earth and rare-earth metals is considered. The coordination facilities and bonding abilities of the fluorenyl ligand, common and less usual synthetic procedures of fluorenyl-based metallocenes of groups 2 and 3 elements, as well as applications derived from these fluorenyl complexes in polymerization and organic catalysis are discussed.
