Formation of Novel T-Shaped NNN Ligands via Rare-Earth Metal-Mediated Si–H Activation
摘要:
Reactions of silylamides [Ln{N-(SiHMe2)(2)}(3)(thf)(2)] with sterically crowded terphenylamine DmpNH(2) (Dmp = 2,6-Mes(2)C(6)H(3) with Mes = 2,4,6-Me3C6H2) afforded via a template reaction the formation of a new tridentate ligand, and derived complexes of composition [LnN{SiMe2N(Dmp)}(2)] (Ln = Ce, Pr) were obtained. Usage of the even more bulky amine Ar*NH2 (Ar* = 2,6-Trip(2)C(6)H(3) with Trip = 2,4,6-iPr(3)C(6)H(2)) yielded the free protonated ligand NH-{SiMe2NH(Ar*)}(2).
