The image shows a "site-selective" Wacker oxidation on a microelectrode array, fabricated(?) by Kevin Moeller's research group. In this experiment, the Wacker oxidation is triggered by using the electrodes in the array to generate a Pd(II) oxidant.

Three synthetic bacteriochlorins (mauve, gold, teal) are each attached to a native-like bacterial photosynthetic β-peptide (green), which self assembles with α-peptide (blue) and bacteriochlorophyll (purple) to form a dyad (top left) and then a cyclic oligomer with enhanced absorption (lower left).  The three constructs can be combined to give cyclic oligomers (top right) with blended bacteriochlorin absorption (lower right) and ~95% energy-transfer efficiency.

Using a pulsed laser, the Michael Gross group photolyzes HO-OH to produce HO• for foot printing solvent-accessible side chains on proteins. The approach, coupled with MS analysis, maps protein interfaces faster than a protein can unfold.

Faculty, doctoral students and undergraduates talk about the department and their experiences at Washington University. From the outset, students get exposed to a broad range of expertise and fields. Interdisciplinary and collaborative research are strengths of this medium-sized department with considerable resources, instrumentation, and facilities.

Azapentadienyl-metal complexes possess two potential sites of reactivity for electrophiles, the nitrogen atom and the basic metal center.  The Bleeke group has investigated the reactions of (1,2,3-η3)-(5-t-butylazapentadienyl)Rh(PMe3)x (x = 2 or 3) and (1,2,3-η3)-(5-t-butylazapentadienyl)Ir(PEt3)x (x = 2 or 3) with triflic acid and has shown that either the nitrogen atom or the metal center can serve as the primary reaction site (see accompanying graphic).

The Hayes and Conradi groups are collaborating on in situ high-pressure high-temperature NMR to monitor the reaction of CO2 as it converts to magnesium carbonate and calcium carbonate.  This work involves WU's Consortium for Clean Coal Utilization
