Why is Pd often "better" at C-H activation than Ni? Just published in JACS, we show that Pd acidifies C(sp3)-H bonds 100,000 times more than Ni. Our DFT collab with @tkschramm.bsky.social and Andreas Hansen @unibonn.bsky.social was crucial to explain acid-base rxns! pubs.acs.org/doi/10.1021/...

I'm excited to share the first publication out of the Brezny lab! We explored some unexpected reactivity of an indole with metalloporphyrins. Thank you to all my awesome students that contributed to this work. pubs.rsc.org/en/content/a...
Mechanism of catalyst activation in iron(porphyrin)-catalysed aerobic oxidative cleavage of 2,3-dimethylindole
Ferric porphyrins catalyse the aerobic oxidative cleavage of 2,3-dimethylindole, mimicking dioxygenase enzymes. The data herein suggest that the indole reduces the FeIII(porphyrin) to FeII(porphyrin) ...

Made the trek to Nuremberg today and rediscovered my sweet tooth!
Renovated half-timbered Franconian house from 1700s in downtown Erlangen. When the style went out of fashion, wooden spikes were embedded to support plaster over the entire wall. Times have changed again! Note the Franconian wooden ceiling.
I made it! Here is the home of Inorganic at FAU where they will graciously let me fumble around. Guesthouse is across the street, shortest work commute I have had in a while!
I’m waiting for take off in CHO on first leg to Germany. I’ll be at FAU Erlangen-Nürnberg for the better part of a year! Looking forward to the adventure and the family joining for Christmas in a month!
Congrats to Emma Cook on her recent publication in Chemical Science! Emma found a lot of interesting nuances in tuning the activity of Mn-based ORR, see for yourself!

There’s been an update to the ACS website for the upcoming dedication the UVA rotunda! Read about some of the early history of chemical education that led to the chemistry department here.
Chemical Hearth - American Chemical Society
The Rotunda, a University of Virginia building designed by Thomas Jefferson, burned down in an 1895 fire, but an important, hidden part of the Rotunda survived: a chemical hearth.
