RESEARCH INTERESTS

Inorganic Chemistry
Dr. Schrodi’s general research interests are in the development of catalysts based on inorganic or organometallic transition metal complexes. Dr. Schrodi’s vision is to contribute to the field of Inorganic and Organometallic Chemistry on fundamental and applied levels, by investigating new ways to activate small molecules and developing catalysts useful in the pharmaceutical and chemical industry.

One area of current research concerns the design and development of novel olefin metathesis catalysts. These catalysts have had a tremendous impact on synthetic chemistry over the past decade. This fact was recognized with the awarding of the 2005 Nobel Prize in Chemistry to Chauvin, Grubbs and Schrock for the development of the olefin metathesis method. Despite the great advances achieved in this field during the past fifteen years, there remain several unmet challenges. Particularly attractive goals include the development of longer-lived ruthenium olefin metathesis catalysts and of catalytic systems based on metals other and less expensive than ruthenium. We are currently working towards these goals.

A second area of current focus is the preparation of new ligands, including highly encumbered N-heterocyclic carbene (NHC) ligands and their applications to reactions catalyzed by late transition metals (e.g., ruthenium, rhodium, and palladium). Since their discovery by Arduengo, NHCs have been widely used to ligate transition metals and have enabled tremendous improvements in transformations such as olefin methathesis and palladium-catalyzed C-C coupling reactions. Larger NHC ligands are often able to impart superior properties to the catalysts that contain them, such as faster initiation, greater stability, and greater selectivity. Therefore, the development of highly encumbered NHC molecules promises to lead to further catalyst improvements and to access novel and reactive low-coordinate NHC-metal complexes.

Finally, a third area of interest involves the design and synthesis of homo- and hetero-multinuclear metal complexes towards the activation and transformation of small molecules (e.g., N2 and CO2).

Our research employs techniques of organic synthesis, inorganic and organometallic chemistry and catalysis, utilizing special equipment (e.g., inert-atmosphere glove boxes, inert-gas/vacuum lines, and modern solvent purification systems of the Grubbs-type) and a wide range of analytical methods (e.g., multinuclear NMR, single-crystal X-ray crystallography, GC, GC-MS, and LC-MS).

In addition to learning these synthetic and analytical laboratory techniques, students in our laboratory will acquire strong skills in areas such as problem solving and proper use of laboratory notebooks. These assets will help them build a successful career in fields like education, academic or industrial research, and medical professions.
