Metastable Metal Complexes Supported by Guanidinate Ligands
In this talk, we describe the chemistry of “metastable” iron and titanium complexes supported by N-donor ligands. We have synthesized a “super bulky” guanidinate that provides kinetic stabilization to reactive metal fragments. To this end, our efforts to synthesize and isolate complexes containing Fe=O/Fe≡N functionalities are discussed. Additionally, we detail our work with titanium supported by guanidinate and imidazolin-2-iminato ligands and describe its reduction chemistry. For example, we have synthesized electron-rich titanium complexes, that when reduced by two-electrons, give access to Ti(II) synthons. These Ti(II) platforms are highly reducing and exhibit unique reactivity. For instance, we observe oxidative-addition of C(sp3)-H bonds which enables catalytic transfer hydrogenation of cyclic olefins. This reactivity and more will be presented.
