Research
It’s not enough to be 3D and aromatic to be 3D aromatic
Misusing the term 3D aromaticity could put chemists on a slippery slope where the concept loses meaning

Research
Unsupervised machine-learning tool could accelerate catalyst discovery
The approach was able to identify phosphine ligands that may form dinuclear palladium(I) complexes using only five experimental data points
-
Research
Textbook electronegativity model fails when it comes to carbon–halogen bond strengths
Computational analysis finds that it’s size, not electronegativity differences, determining bond strength within periodic table groups

Research
Are organic chemists discovering fewer reactions than they were decades ago?
Analysis of millions of transformations reveals reliance on popular methods – and the rise of complex reactions
-
Research
First fundamentally new form of adsorption for more than 90 years driven by molecular machines
Unlike physisorption and chemisorption, the newly discovered ‘mechanisorption’ is an active process that can store energy or chemicals

Research
Exploiting evolution to explore chemical space shows promise for drug discovery
Using molecular trees – similar to family trees – chemists could predict how products will evolve to make new molecules
