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

open access: yesChemistry – 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 ...

It's a Gas: Bioconjugation With Vapor‐Phase Reagents

open access: yesChemistry – A European Journal, EarlyView.
Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion

open access: yesChemistry – 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 ...

Correlative Electron Paramagnetic Resonance Imaging and Atomic Force Microscopy of Lithium Deposited on Copper

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The correlation of a spectroscopic (EPRI) and microscopic (AFM) technique is demonstrated for a sample of Li deposited on Cu. Areas of different morphology were analysed. The techniques complement each other's length scales as well as the information obtained from the sample.
