摘要

Rare-earth elements,including scandium,yttrium,and the lanthanides (La-Lu),possess unique chemical and physical properties,and constitute one of the last frontiers in the periodic table.Rare-earth elements are vital for many high-tech industry products such as smartphones and electric cars.However,the fundamental chemistry of the rareearth elements has been explored to a far less extent.The first organo rare-earth complexes Cp3Ln (1,Figure 1),which bear three cyclopentadienyl (Cp) ligands,were reported in the early 1950s [1],but these complexes did not receive much attention because of the lack of significant reactivity.In the early 1980s,the alkyl and hydride complexes supported by two cyclopentadienyl ligands (such as 2in Figure 1) were reported [2].
