Ortho-metalated, chelate-stabilized benzylamines of the rare-earth metals (RE)
The invention at hand provides, for the first time, thermally stable trisaryl compounds of the rare earth metals which are storable for a long time. These complexes may be produced in situ from the corresponding ortho-lithiated aryl ligands and an anhydrous rare earth metal halide at room temperature and under an inert atmosphere. Benzylamine complexes of the rare earth metals according to the present invention may be used as catalysts for the hydroamination of olefins.<p>
In the context of the present invention, rare earth metals comprise not only 4f elements, but also scandium (Sc) and yttrium (Y).
