The preparation of organometallic derivatives of scandium and yttrium supported by a bulky salicyladiminato ligand from the tris(alkyl) precursors [M(CH₂SiMe₂R)₃(THF)₂] (M = Sc, 1-Sc_R; M = Y, 1-Y_R; R = CH₃, Ph) via alkane elimination was presented. The synthesis and thermal decomposition of bis(ligand) mono(alkyl) complexes was also discussed. It was found that the ancillary ligand provides an adequate level of steric stabilization for the larger yttrium nucleus.
