Formation of Novel T‑Shaped NNN Ligands via
Rare-Earth Metal-Mediated Si–H Activation
Posted on 2014-02-03 - 00:00
Reactions of silylamides
[Ln{N(SiHMe2)2}3(thf)2] with sterically crowded terphenylamine DmpNH2 (Dmp =
2,6-Mes2C6H3 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-Trip2C6H3 with Trip
= 2,4,6-iPr3C6H2) yielded the free protonated ligand NH{SiMe2NH(Ar*)}2.
