Rare-earth metal complexes with tridentate linked amido-indenyl ligand: Synthesis, characterization, and catalytic properties for intramolecular hydroamination

• Complexes of Y, Sm, Er and Yb with a tridentate amido-indenyl ligand were synthesized.
• X-ray single crystal structures of the four complexes were obtained.
• Structure-reactivity study of the complexes was done in intramolecular hydroamination.
• Substrate scope study with various aminoalkenes was done with complexes of Y and Sm.

The complexes of rare-earth metals (Y, Sm, Er and Yb) with a tridentate silicon-linked amido-indenyl ligand were synthesized and characterized. These complexes demonstrated high efficiency in catalyzing the intramolecular hydroamination of non-activated olefins under very mild conditions. Structure–reactivity relationship study revealed that the catalytic activities of these complexes decreased as the radii of the core metal ion decreased.

Four novel rare-earth metal complexes (Y, Sm, Er, Yb) with linked tridentate amido-indenyl ligand was synthesized, characterized and applied to efficiently catalyze the intramolecular hydroamination of non-activated olefins.Figure optionsDownload as PowerPoint slide
