Using Functionalized Silyl Ligands To Suppress Solvent Coordination to Silyl Lanthanide(II) Complexes.

ABSTRACT: The reaction of the potassium 1,3-trisilanediide Me₂Si[Si(Me₃Si)₂K]₂ with SmI₂ and YbI₂ was found to give the respective disilylated complexes Me₂Si[Si(Me₃Si)₂]₂Sm·2THF and Me₂Si[Si(Me₃Si)₂]₂Yb·2THF. Desolvation of coordinated solvent molecules in these complexes made their handling difficult. However, using a number of functionalized silanide ligands, complexes with a diminished number or even no coordinated solvent molecules were obtained ((R₃Si)₂Ln(THF)_x (x = 0-3)). The structures of all new lanthanide compounds were determined by X-ray single-crystal structure analysis. NMR spectroscopic analysis of so
