Reactivity of high-valent iridium nitrides

We have recently prepared terminal nitrides of iridium in the +7 oxidation state.  The goal of this project is to explore the reactivity of these unprecedented species with an eye toward using them to prepare useful nitrogen-containing organic molecules (useful in medicinal chemistry) in catalytic, environmentally sustainable reactions.

Specific aspects of this project that could be pursued include:  (a) Preparing more durable metal nitrides; (b) Carrying out detailed mechanistic studies to understand the nature of reactions with substrates, especially alkenes; (c) Characterizing intermediates of reactions with alkene substrates; (d) Developing reaction conditions to allow catalytic turnover of stoichiometric reactions; and (e) Preparing optically active metal complexes for possible use as enantioselective catalysts.

Techniques learned

Depending on the focus of the project, students will learn skills and techniques in three main areas:  (1) Mechanistic study.  The main skills involved are monitoring reaction kinetics by UV-visible or NMR spectroscopy and handling air-sensitive compounds using a glovebox.  (2) Synthetic chemistry.  Both synthetic organic techniques and synthetic inorganic techniques are relevant; x-ray crystallography is a commonly used method to characterize novel compounds.  (3) Physical inorganic chemistry.  This involves the use of various kinds of spectroscopy (UV-vis-NIR, IR, EPR, XPS, variable-temperature NMR) to characterize and elucidate the electronic structure of the metal nitrides and other compounds.  Interested students can also learn computational methods for clarifying electronic structure and spectroscopic properties.
