My work assessing the effect of preorganization on dihydrazide activity is out in @jacs.acspublications.org. We find that dihydrazides with flexible tethers can replicate much of the catalytic activity of complex dihydrazides with preorganized foldamer scaffolds. #Chemsky

Bifunctional Catalysis of Aldol Reactions by Foldamer Dihydrazides: Assessment of Conformational Preorganization

We previously reported that molecules containing two cyclic hydrazide units connected by a polymethylene linker could catalyze aldol condensations via a bifunctional mechanism. One hydrazide apparentl...

Controversial quantum-computing paper gets hefty correction — but concerns linger

The journal Science has lifted an expression of concern on a paper claiming evidence of Majorana quasiparticles and added new details.

#chemsky, have you used a Wisconsin Photoreactor? I designed them and will soon defend my PhD. I’d like to include photos of Wisconsin Photoreactors in use by other chemists in my defense. Please share (reply to this post or DM me) a photo of your photoreactor in action!

Versatile Open-Source Photoreactor Architecture for Photocatalysis Across the Visible Spectrum

Adoption of commercial photoreactors as standards for photocatalysis research could be limited by high cost. We report the development of the Wisconsin Photoreactor Platform (WPP), an open-source phot...

My work on bifunctional organocatalysis of aldol reactions by flexible dihydrazides is out in JACS (@pubs.acs.org). I find that hydrazide units connected by long, flexible linkers offer significant rate enhancement relative to monohydrazides. doi.org/10.1021/jacs... #ChemSky

Dual Activation Modes Enable Bifunctional Catalysis of Aldol Reactions by Flexible Dihydrazides

Hydrazides are known to catalyze reactions of α,β-unsaturated aldehydes via transient iminium formation. The iminium intermediate displays enhanced electrophilicity, which facilitates conjugate additi...
