Nowadays, the synthesis of the lanthanide hydrides is less challenging, the experimental conditions for their formation are known and their reactivity has been widely investigated. During the last two decades, lanthanide catalysis has been extensively explored [3], considering the unique properties and the absence of toxicity of these "heavy This charpter summerized the main progress in organolanthanide chemistry in recent years, including the synthesis and reactivity of organolanthanide π‐complexes stablized by cyclopentadienyl and subs The reaction of [O(CH 2 CH 2 C 5 H 4) 2]LnCl with NaH in THF at 45°C generates the dimeric organolanthanide hydridges, [O(CH 2 CH 2 C 5 H 4) 2 LnH] 2 (Ln = Gd, Er, Yb, Lu, Y), in good yield. These new complexes have been fully characterized by elemental analyses, mass spectrometry, IR and NMR spectroscopy. The hydrides cn react with alknes and ://   Reductive Reactivity of the Organolanthanide Hydrides, [(C5Me5)2LnH]x, Leads to ansa-Allyl Cyclopentadienyl (η5-C5Me4CH2−C5Me4CH2-η3)2- and Trianionic Cyclooctatetraenyl (C8H7)3- Ligands.

A very important point that was not well understood The effects of the bridging chain and the central metal upon the reactivity of organolanthanide hydrides generated in situfrom the [Ln(C 5 H 5) 2 Cl]–NaH system were investigated. The reactivity can be tuned not only by varying the ligands but also by taking advantage of the lanthanide contraction. The ligand tunability varies for different

  This paper reviews the advances in substituted cyclopentadienyl and bridged bis (cyclopentadienyl)organolanthanide chemistry,including the study on synthesis,structure and reactivity of organolanthanide Hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. The three major groups are covalent, ionic, and metallic hydrides. Formally, hydride is known as the negative ion of a hydrogen, H-, also called a hydride ion. Because of this negative charge, hydrides have reducing, or basic :// /Main_Group_Reactions/Compounds/Hydrides.
