Ortho-metalated, Chelate-stabilized Benzylamines of the Rare Earth Elements (RE)

The present invention describes homoleptic, ortho-metalated complexes of rare-chelatstabilisierte benzylamine. 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 novel complexes at least one benzylic proton of the benzylamine ligand by an alkyl or aryl group is replaced.Preferred are those complexes in which both protons of the benzylic Benzylaminliganden by alkyl or aryl groups are substituted. Inventive complexes are prepared by reaction of rare earth with chelatstabilisierten ortholithiierten aryl ligands at room temperature under inert gas atmosphere. The novel complexes are thermally stable and are suitable as catalysts for the hydroamination of olefins.
