I'm sad that, at least based on the Bluesky search box, this is the most recent RevMed post.

🌻Rest in peace, Günther Maier. The chemist who made one “impossible molecule” after another died on April 10 at the age of 94. He was a modest man who trained a large number of PhD students. His achievements were recognized with the Adolf von Baeyer Memorial Medal of the GDCh. l-i-c.org/1125

Excited to share the groups most recent cluster based work by first-author Linh Le, and collaboratively with @annawuttig.bsky.social and @gagliardilaura.bsky.social groups. Iron-sulfur clusters can serve as direct electrocatalysts for carbon dioxide reduction!

If you like harnessing carbenes from di-chlorides, you’ll LOVE skeletal editing with tri-chlorides!

Back in 2019 I wrote my first grant, for the ACS PRF, in which I proposed carbon insertion into LSD (truly a pipe dream at the time). After teaming up with @nagiblab.bsky.social and @deolsonlab.bsky.social, the dream is finally a reality!

A text image of a small part of the transcript of a conversation between Ari Shapiro and David Simon (Creater of 'The Wire') on a segment on NPR during the wirter's strike of 2023:

Shapiro: OK, so you've spent your career creating television without AI, and I could imagine today you thinking, boy, I wish I had that tool to solve those thorny problems...

Simon: What?

Shapiro: ...Or saying...

Simon: You imagine that?

Shapiro: ...Boy, if that had existed, it would have screwed me over.

Simon: I don't think AI can remotely challenge what writers do at a fundamentally creative level.

Shapiro: But if you're trying to transition from scene five to scene six, and you're stuck with that transition, you could imagine plugging that portion of the script into AI and say, give. me 10 ideas for how to transition this.

Simon: I'd rather put a gun in my mouth.

Potassium tert-Butoxide: Solubility, Solution Structure, and Reactivity Fundamental properties including solubility and structure–reactivity correlations of potassium tert-butoxide (KOtBu) are described in this manuscript. A combination of donor solvent titration, diffusion NMR, and DFT studies established that KOtBu exists in one of three solution structures: (1) unsolvated cubic tetramer in non-Lewis basic solvents, (2) disolvated cubic tetramer in Lewis basic solvents, and (3) solvated monomer in protic solvents. These studies dispel the notion that strong aprotic donor solvents lead to deaggregation of KOtBu cubic tetramer. In DMSO, a concentration-dependent equilibrium mixture of bis-DMSO-solvated cubic tetramer, dimsylpotassium, and tert-butanol is formed. Donor solvent association with potassium was contextualized in terms of periodic trends within the alkali metal series. The previously reported 1:1 complex of KOtBu and tert-butanol was found to be highly insoluble and affords poor availability of KOtBu when employed in a model dehydrohalogenation reaction. Reactivity can be recovered by the inclusion of strongly Lewis basic donor solvents that disproportionately stabilize the transition state.

So you think you know KOtBu…
Well my colleagues in #PfizerChemistry process chem have done some amazing work to find out a lot more about a very useful base #ChemSky

@merz.bsky.social I read the latest "AI is coming" manifesto by Shumer and was genuinely confused to read a prediction that was a ~year old that did not happen - and it is surprising to me that these folks don't recognize how damaging it is to their credibility

Pro-LLM academics bemoaning how long it takes to write and review papers are telling on themselves. Those tasks are supposed to take a long time because that's how you can be thoughtful, thorough, and rigorous.

Filtering yourself is how you only communicate things you think are worth reading.

Publishers are already seeing unprecedented quantities of AI slop and unethical AI use by authors and reviewers, and it's terrifying that tools like this will open the floodgates further. Gen AI is a plague and I wish it a swift death.
