Research Interests:
Research in the Speed group focuses on the boundary of synthetic organic chemistry and main-group chemistry. Synthesis is the building up more complex molecules from simpler ones. We specialize in catalyst design, including asymmetric catalysis, and the chemistry of heterocycles (ring-shaped molecules that contain atoms other than carbon). Many transformations we target involve the synthesis or transformation of nitrogen-containing compounds, and sulfur-containing heterocycles. These structural motifs are of immense importance in the pharmaceutical industry.
Our catalysts contain non-metallic main-group elements such as boron or phosphorus, often surrounded by unusual ligands to promote the desired reactivity. Frequently, preparation of the catalysts we investigate has required development of new strategies in main-group chemistry. Many processes under investigation in our group also involve unpaired electrons and photoexcitation, but again with a focus on main-group chemistry.
