Research Interest Summary:

C-H and C-F Bond Activation By Nickel Complexes.
The development of methodologies for the use of relatively inexpensive 1st row transition metals, such as nickel, in C-H and C-F bond activation could revolutionize the importance of such reactions in chemical synthesis; unfortunately both kinetic and thermodynamic issues render this advancement difficult. Our group is working to demonstrate that through ligand design complexes that are capable of the selective activation of these bonds is possible.

Through-Space Interactions and Clusters by Design.
Communication between metal centers is central to a variety of important applications in chemistry. Electron transfer, magnetic properties and a plethora of catalytic applications rely on interactions between metal centers, mediated either by their close proximity or bridging ancillary ligands. In a series of publications, our group has demonstrated the capability of the triamidophosphine ligands, P(CH2NArR)3 (where ArR is an aryl substituent) to allow for the facile assembly of polynuclear complexes and polymers, as well as mediate through-space interactions.
