Over the last few decades, homogeneous molybdenum catalysis has been a center of interest to inorganic, organic, and organometallic chemists. Interestingly, most of the important advancements in molybdenum chemistry such as non-classical dihydrogen coordination, dinitrogen reduction, olefin metathesis, and water reduction utilize diverse oxidation states of the metal. However, employment of redox non-innocent ligands to tune the stability and reactivity of such catalysts have been overlooked. With this in mind, the Trovitch group has developed a series of novel bis(imino)pyridine (or pyridine diimine, PDI) and diimine (DI) ligands that have coordinating phosphine or amine arms to exert coordination flexibility to …

Nanoporous crystalline oxides with high porosity and large surface areas are promising in catalysis, clean energy technologies and environmental applications all which require efficient chemical reactions at solid-solid, solid-liquid, and/or solid-gas interfaces. Achieving the balance between open porosity and structural stability is an ongoing challenge when synthesizing such porous materials. Increasing porosity while maintaining an open porous network usually comes at the cost of fragility, as seen for example in ultra low density, highly random porous aerogels. It has become increasingly important to develop synthetic techniques that produce materials with these desired properties while utilizing low cost precursors and increasing …
