Worth experimenting with dough rising for that famous New York no-knead bread recipe. This one is by rising the dough in the fridge for 4 days. It is a completely different taste from the regular 12-18 hour option. Way better, more subtle…

Can one apply Le Chatelier principle to a transition state?

Me: sounds kind of weird

Also me: in this class let me tell you about transition state theory. It assumes that there is an equilibrium between reactants and transition state

9 years ago I determined the complete structure of the borolithochromes, which are enigmatic boron-containing pigments from a Jurassic fossil. Unbelievable to see that our reported structures of these ancient molecules get confirmed now by total synthesis: onlinelibrary.wiley.com/doi/10.1002/an…

Acetoacetic ester, known since the 19th century, is central to chemistry. Now we have scanned it with boron. Spearheaded by Alina, ⁦Diego Diaz⁩. Special thanks to Travis Dudding and his team for theoretical backing of claims. onlinelibrary.wiley.com/doi/10.1002/an…

Little-known fact: a sulfiliminium has a pKa ~ 8.
A poll: is a sulfilimine bio-isosteric for a sulfoxide (i.e. Ki's will be within 10x, i.e. <1.4 kcal)?
To test: compare a classic toxin (amanitin) & a drug (Fulvestrant) with their sulfilimine congeners.
We're about to find out..

When we publish isolated yields in chemistry, there is an assumption that they have been obtained by a human, right? If not, maybe this should be spelled out.
