Homoleptic Chiral Benzamidinate Complexes of Rare‐Earth Elements: Synthesis, Structure, Luminescence, and Magnetism

The new enantiopure amidinate (S,S)-N,N′-bis[1-(2naphthyl)ethyl]benzamidinate [(S)-NEBA] was introduced into the chemistry of the rare-earth elements. Firstly, the synthesis of the corresponding amidine [(S)-HNEBA] is described. Amine elimination reactions of (S)-HNEBA with [Ln{N(SiMe3)2}3] [Ln = Y (1), Sm (2), Tb (3), Dy (4), Er (5), Yb (6), Lu (7)] gave a series of enantiomerically pure homoleptic rare-earth metal complexes
