The viability of these small-scale samples as starting materials for amide and cyclopentadienyl f-element complexes was tested by reacting KN(SiMe3)2, KCp′ (Cp′ = C5H4SiMe3), KCp′′ (Cp′′ = C5H3(SiMe3)2-1,3), and KC5Me4H with 1-Ln generated in situ. These reactions produced Ln[N(SiMe3)2]3 (4-Ln), Cp′3Ln (5-Ln), Cp″3Ln (6-Ln), and (C5Me4H)3Ln (7-Ln), respectively. Small-scale
