(NH4)2[Tc2O2(S2O7)4]: An Unexpected Technetium(V)‐Sulfate From the Reaction of (NH4)(TcO4) With SO3

Chemistry – A European Journal, EarlyView.
The reaction of the radioactive pertechnetate (99TcO4)− with the oxidizer SO3 leads to blue crystals of (NH4)2[Tc2O2(S2O7)4]. The complex dimeric [Tc2O2(S2O7)4]2− anion exhibits the technetium in the oxidation state V, showing that reduction occurs during the reaction.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

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.
