Innovating Electrosynthesis From Metal Electrodeposition to Organic Chemistry: Deep Eutectic Solvents as Efficient and Sustainable Media

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
This review analyzes deep eutectic solvents (DESs) as efficient media for both organic and inorganic electrosynthesis. The improvements in terms of synthetic opportunities and sustainability are discussed, by exploring the multiple roles of DESs as solvents, electrolytes, and promoters, enabling effective and selective electrosynthesis under mild and ...

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
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 ...

Selective Oxidation of Primary Amines to Nitriles Catalyzed by the Ru‐Doped Hexagonal Perovskite SrMnO3

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
The selective oxidation of primary amines to generate nitriles provides a cost‐effective and atom‐economical synthetic approach that avoids the formation of harmful byproducts. However, achieving high yields under mild conditions remains challenging, due to the difficulty in efficiently activating the α‐CH bonds of amines and the multiple competing ...
