Title: “Unusual Observations in Nitrene Chemistry”

Abstract:

Nitrenes are high-energy intermediates that enable challenging transformations such as C-H insertion, de-aromatization and rearrangement processes. Yet, nitrenes often exhibit poor chemoselectivity profiles. As a result, nitrene or nitrenoid-mediated processes typically employ stabilizing groups, such as carbonyl and sulfonyl substituents, or transition metals, in order to promote one desired reaction pathway. In the Williams lab, we are exploring boron and phosphorus(III) as stabilizing agents which can electronically alter the behavior of nitrenes. Our studies have resulted in an unusual synthesis of anilines arising from borylnitrene C-H insertion reactions. Experiments show complete selectively for aryl C-H bonds, with no reaction at the expected benzylic position. Further, the identity of the boron ligands is intrinsically connected to a chemoselectivity switch in the reaction.

Title: “Dusty Skies and Dirty Buildings: Adventures in Atmospheric Photochemistry”

Abstract:

Over a billion tons of photoactive dust are released into the atmosphere every year from deserts and other arid environments. After emission, this dust undergoes transport to distant urban regions, where it can mix with local pollution sources and settle on building surfaces, which are themselves potential substrates for photochemistry. Although studies have shown that reactions on environmental surfaces can influence the lifetime of surface-sorbed pollutants and the atmospheric abundance of reactive trace gases, our understanding of photochemistry on dust and urban surfaces is far from complete. In this seminar, I will outline our group’s approach to studying these complex systems, and highlight some of our recent discoveries.

Title: “New Metal-Mediated Cross-Coupling Reactions: Making Great Reactions Even Better”

Abstract:

Cross-coupling reactions promoted by transition metals are among the most commonly used synthetic transformations by chemists in virtually all subdisciplines. The various flavors of Pd-catalyzed arylation reactions have revolutionized how functional molecules are prepared, even to the point of the fragments derived from these reactions being overexpressed in active pharmaceutical ingredients. The development of Pd-catalyzed cross-coupling reactions received the Nobel Prize in 2010, but there remain many challenges to be addressed and new coupling manifolds to be discovered. This seminar will discuss some of the most pressing challenges and highlight some solutions that we have uncovered.

CIC Edmonton Planning Retreat

On June 20, members of the CIC Edmonton Section’s executive held their annual retreat to plan events for the following year. We are always seeking new members to participate in planning events and activities to promote chemistry in the Edmonton region with us! (And it’s actually lots of fun!)

Here are two photos of the folks that made it out:
