摘要：

A new series of bis-ligated organolanthanide amides, (1)2-LnN(SiMe3)(2)center dot C7H8 (Ln = Sm (2), Y (3), Yb (4)), have been prepared by the reaction of Ln[N(SiMe3)(2)](3) with the ligand (S)-2-(pyrrol-2-ylmethyleneamino)-2'-(dimethylamino)-1,1'-binaphthyl (1H) in good yields. They are active catalysts for the asymmetric hydroamination/cyclization reaction of aminoalkenes, affording cyclic amines in moderate to good conversions with moderate to good ee values.
