Areas of Research/Expertise 

We have extensively used rational ligand design to control the synthesis and reactivity of main-group and transition metal organometallic and coordination complexes. We have also investigated steric effects on the reactivity and magnetic/electrochemical properties of metal complexes, and synthesized precursors to materials with desired electronic/optical properties. Most recently, we are conducting research into the mechanochemical synthesis of organometallic complexes of the s-, p-, and d-block elements, including those with bulky allyl ligands. The grinding or ball milling of reagents provides access to compounds that are not available through conventional solution-based methods, including those with potential catalytic applications. Two particular areas of mechanochemical interest are: 1) the synthesis of low-coordinate metal complexes, as they can display higher reactivity than comparable solvated species, and 2) the control of stereochemistry in solid-state synthesis.
