Features of organolanthanide complexes, these features on a molecular level and under anaerobic conditions is discussed, including thermodynamic and kinetic considerations. Due to the importance of a prolific metal/ligand synergism, current developments in ligand design are emphasized.作者: 積云 時間: 2025-3-22 19:17 作者: left-ventricle 時間: 2025-3-23 00:08 作者: Toxoid-Vaccines 時間: 2025-3-23 01:41
Rare earth complexes with heteroallylic ligands,ery promising alternatives for cyclopentadienyl ligands in lanthanide chemistry. In particular, the easily accessible .-silylated benzamidinate ligands [RC.H.C(NSiMe.).]. may soon rival C.H. and C.Me. in their high versatility.

Routes to monomeric lanthanide alkoxides,. Special emphasis is put on the design and synthesis of tailor-made ligand environments. In particular, the methodology of donor-functionalization opens the way to creating several intriguing properties simultaneously — prerequisites for potential applications as highly selective catalysts for orga作者: 核心 時間: 2025-3-23 10:02
Lanthanide metallocenes in homogeneous catalysis,e complexes such as (C.Me.).LnCH (SiMe.). and [(C.Me.).Ln(.-H)]. play a key role as precatalysts in organolanthanide mediated reactions. The design and synthesis of such complexes is outlined first. This is followed by a description of various processes catalyzed by lanthanide metallocenes such as o作者: 特征 時間: 2025-3-23 14:40
