Abstract By using the β -diketiminato ligands bearing pendant nitrogen or oxygen donors, a series of rare-earth metal complexes containing reactive metal-bound functionalities have been synthesized. The most notable is the synthesis of subvalent scandium complex, scandium terminal imido complexes, four-coordinate scandium phosphinidene complex, non-pincer-type mononuclear scandium alkylidene complexes, scandium nitrilimine complex, yttrium hydride-PhSiH 3 complex, and dialkyl complexes with larger rare-earth metal ions. The reactivity and catalytic activity of rare-earth metal complexes of β -diketiminato ligands bearing pendant donors are also briefly reviewed.
