    • The present invention describes homoleptic, ortho-metalated, chelate-stabilized benzylamine complexes of the rare-earth metals. The rare-earth metals are selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu. In the complexes according to the present invention, at least one benzylic proton of the benzylamine ligand is replaced by an alkyl or aryl group. Such complexes are preferred in which both benzylic protons of the benzylamine ligand are replaced by an alkyl- or aryl group. The complexes according to the present invention are produced by reaction of chelate-stabilized rare-earth metal halides with ortho-lithiated aryl ligands at room temperature under inert gas atmosphere. The complexes according to the present invention are thermally stable and suitable for being used as catalysts for the hydroamination of olefins.
    • 本发明描述了稀土金属的均聚,邻位金属化,螯合稳定的苄胺络合物。 稀土金属选自Sc,Y,La,Ce,Pr,Nd,Pm,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu。 在根据本发明的络合物中,苄胺配体的至少一个苄基质子被烷基或芳基取代。 这种络合物是优选的,其中苄胺配体的两个苄基质子都被烷基或芳基取代。 根据本发明的络合物通过螯合稳定的稀土金属卤化物与邻位锂化的芳基配体在室温下在惰性气体气氛下反应来制备。 根据本发明的络合物是热稳定的并且适用于用作烯烃的水解的催化剂。
