Notes:
The reactions of Lnl33 (Ln = La, Ce, Er, Yb) with sodium silanolate (NaOSiMe3) in THF at room temperature yield lanthanide silanolates Ln(OSiMe3)3 which seem to be oligomers with μ-OSiMe3 ligands. Reaction of Cel3 with potassium siliconate, KO[Me1.96Ph0.04SiO]20.75K, yields a netted polymer [Me61.59Ph1.29Si31.44O39.02Ce]x. An analogous procedure which involves reaction of Lnl3 (Ln = Ln, Er) with KO[Me1.96Ph0.04SiO]50.00 K, and following treatment with NaOSiMe3, results in the formation of solublé product (Me3SiO)2LnO[Me1.96Ph0.04SiO]50.00 Ln(OSiMe3)2.
