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) ...
