NewsGerman firms raided over dual use chemicals sent to Russia
Companies have reportedly been exporting substances that could be turned into chemical weapons for several years without a permit
-
ResearchMultitasking boron catalyses first aldol reaction from esters
Using esters instead of aldehydes offers chemists a completely new retrosynthetic disconnection
-
ResearchClever carbene synthesis replaces notoriously hazardous chemistry
Reactive carbon compounds can now be made from aldehydes instead of explosive or unstable reagents
-
ResearchRich chemistry revealed by tip microscopy pulses’ bond making and breaking
Using an STM, scientists have been able to precisely switch between three different molecules, opening the way to multiple selective transformations
-
ResearchElectrocatalytic hydrogen atom transfer could give industrial organic synthesis a boost
The new approach – inspired by decades of energy storage research – is selective, efficient and sustainable
-
ResearchIt’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
-
ResearchCatalytic alchemy sees device transform one metal so that it behaves like another
Electric charge enables the catalytic ‘speed limit’ for many important reactions to be bypassed
-
ResearchLunar soil shows promise as a catalyst for extraterrestrial photosynthesis
Moon rock could one day be used to accelerate water splitting and carbon dioxide conversion in space to support crewed missions

ResearchRobot chemist snaps 3D building blocks together like Lego to make complex molecules
Automated synthesiser uses a new class of boronates that are a thousand times more stable than those previously used
-
ResearchNew microscope makes tracking chiral molecules in live cells possible
The instrument uses circularly polarised light to tell left- and right-handed species apart and monitor them in space and time
-
ResearchUnsupervised 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
-
ResearchTextbook 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
-
ResearchAre 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
-
ResearchFirst 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
-
ResearchExploiting 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
