Reaction of anhydrous YbCI 3 with 1 equiv. of LLi [L= p ‐CIPhNC(Me)CH(Me)N(C 6 H 3 ‐ ‐ 2,6‐i‐Pr 2 )] in THF at room temperature gave the diketiminate lanthanide dichloride LYbCl 2 (THF) 2 (1) in good isolated yield. Similarly reaction of anhydrous YbCI 3 with 1 equiv. of LLi, then with I equiv. of t ‐BuCpNa in THF yielded the expected mixed‐ligand β‐diketiminate ytterbium chloride ( t ‐BuCp)YbL(μ‐CI) 2 Li(THF)I (2). Both 1 and 2 were well characterized by elemental analysis, IR spectra, 1 H NMR spectra, and X‐ray diffraction analysis.
