Organometallic Chemistry of the Lanthanide Metals

Bulky Formamidinate-Supported Lanthanoid Halides and Alkyls, Including a Rare Terminal La–Me Species

“…Organolanthanoid halides LnR n X 3– n are often target molecules in synthetic organolanthanoid chemistry, since they are possible isolable products directly from metathesis reactions between lanthanoid trihalides and alkali-metal salts of anionic organic ligands . Such organolanthanoid halides are key starting materials for derivatization to give other organolanthanoids, including alkyl, hydride, organoamide, and alkoxide complexes LnR n Z 3– n (Z = R′, H, NR′ 2 , OR′).…”

Tris(carbene)borates; alternatives to cyclopentadienyls in organolanthanide chemistry

“…cyclobutadienide, cyclononatetraenide. [7][8][9][10][11][12][13] Lanthanide organometallic complexes have demonstrated exciting properties, from single-molecule magnetism [14][15][16][17] and molecular qubit behavior [18][19][20] to reductive activation of small molecules 21,22 and photocatalytic properties. 23,24 New robust, monoanionic, and sterically bulky alternatives to these cyclic ligand sets should further expand the capabilities of molecular f-block compounds.…”

Photocatalytic dechlorination of unactivated chlorocarbons including PVC using organolanthanide complexes

“…15 Spectroscopic measurements confirm that the four compounds 2-Ce, 4-Ce, MgBn2(THF)2 and MgCp tet 2 are all present in equilibrium in solution at the start of the reaction. 29 A reaction of 2-Ce with a 20-fold excess of MgBn2(THF)2 results in a mixture of these products with a calculated equilibrium constant of 2.5 for the equation in Figure 3, top. Product yields for both 2-Ce and 3-Ce are higher at lower catalyst loadings, which we attribute to the greater effective concentration of MgBn2(THF)2 that pushes the equilibrium towards the active species 4-Ce (see ESI).…”
