Recent advances in alkoxo and aryloxo chemistry of scandium, yttrium and lanthanoids

Anionic coordinated polymerization ofɛ-caprolactone with aluminium, zirconium and some rare earths alkoxides as initiators in the presence of alcohols

“…The chemistry of lanthanide alkoxides is nowadays welldocumented 17,41) . These compounds are known to form pentanuclear complexes with oxo ligands of general formula Ln 5 (l-O)(OiPr) 13 and the monomeric species are generally unstable, unless using bulky ligands.…”

Synthesis and Structural Characterization of Tetra‐ and Pentanuclear Lanthanide Hydroxido Clusters

“…One way to obtain these compounds is the hydrolysis of moisture-sensitive starting material, [11,12] whereas the other approach is a hydrolytic one in which the water molecules are deprotonated in a controlled way. [13][14][15][16][17][18] Most of the oxido/hydroxido clusters are stabilized by ligands such as alkoxides, [19,20] phenoxides, [21] diketones, [22,23] and more recently amino acids [7,24] and the o-nitrophenolato ligand.…”

Gas-phase transuranium chemistry: reactions of actinide ions with alcohols and thiols

“…In the condensed phase, the electropositive lanthanides react with alcohols, ROH, to generate the ionic trivalent alkoxides, Ln(OR) 3 . 21 Gas-phase reactions of lanthanide ions, Ln C , with alcohols have produced oxides, hydroxides, alkoxides, aryloxides, aldehydes and dehydrogenation complexes. 22 -25 The reaction pathways of the various Ln C can be interpreted in the context of electronic configurations and ionization potentials, and the ultimately produced products, such as Ln(OCH 3 2 C , typically reflect the high oxophilicity and distinct propensity of most lanthanides to exist in a trivalent state.…”
