Syntheses and Reactivity of Yb and Sm Inverse Sandwich Arene Complexes.

ABSTRACT: Inverse sandwich arene complexes of rare earth metals have gained notable interest due to their unique electronic properties. In these complexes, an arene ligand bridges two metal centres, storing 0, 2, or 4 electrons, which is the basis for unique reactivity. Herein, we report on the reactivity of [(^DIPePBDI)Ln]₂(η⁶,η⁶-benzene) (II-Ln, Ln = Yb or Sm) and in situ reduced [(^DIPePBDI)SmI]₂ (V) (^DIPePBDI = HC[C(Me)N-DIPeP]₂, DIPeP = 2,6-CHEt₂-phenyl). The Yb^II-benzene^2--Yb^II complex (II-Yb) reacted smoothly with biphenyl, naphthalene, anthracene, and COT, giving a range of new Yb^II complexes with bridging arene or COT ligands. However, due to much stro
