The reactions of (R)-(+)-2,2′-bis(cyclopentylamino)-1,1′- binaphthyldiamine with [Li(THF)n]3[LnMe6] (Ln = La, Sm) in THF at 0 °C depending on the metal ion size result in the formation of trinuclear [(R)-C20H12(NC5H 9)2]Sm[(μ-Me)2Li(THF)2(μ-Me) Li(THF)] (1) or tetranuclear [(R)-C20H12(NC 5H9)2]La{(μ-Me)2Li(THF)[(μ-Me) Li(THF)]2} (2) complexes with methyl ligands μ-bridging lanthanide and lithium atoms. The structures of complexes 1 and 2 were established by single-crystal X-ray diffraction and solution NMR studies. These new complexes were evaluated as catalysts to promote the enantioselective hydroamination of amino-1,3-dienes.
