Research Interests:

Our group is interested in the study of small molecule transformations assisted by transition metal complexes. Projects include:

  1. Study of first-row transition metal complexes of tetrapodal pentadentate ligands composed of N-heterocyclic carbenes, particularly in relation to small molecule activation and group transfer reactions.
  2. Transformation of C-1 substrates (CO, CO¬¬¬¬2) to value added products using first-row transition metals.
