  A series of new homoleptic rare-earth-metal complexes was   synthesized using salt metathesis reactions between   LnCl3 and α-K(DMBA) (Ln = La (1), Ce   (2), Pr (3), Nd   (4), Sm (5), Gd   (6), Y (7); DMBA =   N,N-dimethylbenzylamine). All seven complexes were found   to be free of coordinating solvent, and no formation of any   “-ate” species was observed. The ligands in complexes   17 displayed η4  coordination to the metal center. Subsequently, the reactivity of   1 and 7 was investigated via   various protonolysis reactions using silylamines, anilines, and   phenols to generate a diverse array of other homoleptic   lanthanide complexes.
