Research by the Hollis and Webster groups was recently featured on the cover of the ACS journal Organometallics.
Improving imido ligand reactivity in transition metal complexes through π-loading was originally applied to C–H bond activation for methane, but recently has seen renewed interest for a broader range of applications. A bent bis(imido)Ta fragment has three open coordination sites, and the monoanionic CCC-NHC pincer ligand provides a spatially aligned, strong donor for each. Thus, the maximal orbital interactions, or extreme π-loading, are accomplished providing a complex that, despite the presence of LiI, catalyzes oxidative amination/transfer hydrogenation involving a C–H bond activation.
The cover art was produced by MSU's Anna Zollicoffer, based on a concept by Ted Helgert, a postdoc in the Hollis group.
