The Future of Foundation Machine Learning Potentials and DFT in Homogeneous Catalysis: Competition or Synergy?

Chemistry – A European Journal, EarlyView.
Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

Chemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable

Light‐Induced Anion Translocation to Control Helical Folding in an Artificial Communication System

Chemistry – A European Journal, EarlyView.
Anion‐induced helical folding of an oligomer is controlled indirectly and reversibly by light through anion uptake/release by a photoresponsive receptor. Thus, a light signal is processed into a chemical signal in a communication‐type three‐component supramolecular system.

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives

Chemistry – A European Journal, EarlyView.
Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...

Catalyst‐Free Cyanation of Arenes by Acetonitrile in a Plasma–Liquid Microreactor

Chemistry – A European Journal, EarlyView.
An original approach of arylnitrile synthesis was developed by generating an argon plasma in contact with solutions of arene in acetonitrile within a gas‐liquid microreactor. Plasma activation of acetonitrile generated cyano radicals, enabling a catalyst‐free C‐H cyanation of arenes.
