A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Ladder‐Like Structural Architecture of Layered Magnetic A2.4 Cr8Te14 (A = Rb, Cs) Compounds by Self‐Flux Synthesis

Chemistry – A European Journal, EarlyView.
A2.4Cr8Te14$A_{2.4}{\rm Cr}_{8}{\rm Te}_{14}$ (A = Rb, Cs) compounds exhibit a layered, ladder‐like Cr‐Te framework uniting structural motives of hollandite‐like and delafossite‐like phases. Alkali atoms are situated both in the interlayer space and tunnels within the Cr8Te14${\rm Cr}_{8}{\rm Te}_{14}$ framework.

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion

Chemistry – A European Journal, EarlyView.
Thermal amidation between a carboxylic acid and an amine was successfully conducted in an extruder in the absence of solvent, coupling agent, or catalyst, relying on an adapted Bayesian Optimization protocol. Active pharmaceutical ingredient moclobemide was synthesized on a larger scale, achieving excellent yield and low Process Mass Intensity (PMI ...

When Light Challenges Heat: Mechanistic Insights Into a Reaction Competing With Cadogan Cyclisation in Nitro‐Perylenediimides

Chemistry – A European Journal, EarlyView.
Visible‐light irradiation of nitro‐perylenediimide in the presence of triphenylphosphine reveals an unexpected pathway competing with the classical Cadogan cyclization. Mechanistic investigations uncover the rapid and selective formation of bay‐functionalized 1‐iminophosphorane‐12‐hydroxy perylenediimide derivatives.
