The synthesis and characterization of rare-earth half-sandwich naphthalene and metallacycle complexes supported by a ferrocene diamide ligand (NNTBS) are reported. Easily synthesized precursors (NNTBS)LnI(THF)x and a reducing agent (KC8) allow for the isolation of half-sandwich complexes, Ln-naph-K. These prepared naphthalene compounds serve as reducing agents. In the presence of diphenylacetylene, five-membered rare-earth metallacycles, Ln-C4Ph4-K, are formed. These new metal complexes are characterized by X-ray crystallography and multinuclear NMR spectroscopy.
