Outline of Final Research Achievements |
In this research project, we designed and synthesized precursors for low-coordination, low-valent complexes of early transition metals by utilizing sterically encumbered phenoxide ligands. For example, reduction of a zirconium dichloride complex bearing two bulky phenoxide ligands in toluene led to formation of a toluene-bridged inverted-sandwich dizirconium complex according to X-ray diffraction and NMR spectroscopic studies. This dinuclear complex was found to behave as a source of a low-coordination zirconium and a multi-electron reductant along with toluene extrusion. The inverted-sandwich complex was treated with alkyl azide to generate a mononuclear imide complex, where organic azide underwent two-electron reduction.
