ChemCatChem, EarlyView.Perester‐type species on the CO oxidation catalyzed by gold‐based nanoparticles is a key intermediate for efficient catalysis. The high spin electronic state of the Au–Ru cluster favors oxygen molecule barrierless dissociation upon adsorption. Charge accumulation on Ru enhanced by charge transfer enhanced O─O bond activation.

Direct Coumarin Synthesis by Gold Catalyzed Hydroarylation of Alkynoic Acids/Esters
ChemCatChem, EarlyView.Gold‐catalyzed, direct hydroarylation of alkynoic acids (or esters) with phenols in a small amount of an ionic liquid as solvent and reaction promoter provides an efficient pathway for the one‐pot preparation of coumarins. This synthetic methodology is highly atom efficient, works with <1 mol% gold and the catalytic system is recyclable.

Cannabigerol Extraction from a Cannabis Cultivar Using a Supercritical Carbon Dioxide Process
Chemical Engineering &Technology, EarlyView.The aim of this work was to assess for the first time the supercritical fluid extraction (SFE) process feasibility to obtain a CBG‐rich extract from Cannabis. Extraction experiments highlighted that CBG can be properly extracted at 18 MPa and 40 °C and the extraction plant scheme affected CBG recovery and purity.

Mechanistic Insights into the Early Stages of Oxidation at Copper Terrace: The Role of O-O Repulsion and Substrate-mediated Effects [PDF]
arXivCopper-based catalysts play a crucial role in industrial oxidation reactions. Although many theoretical studies consider copper to be metallic, it is well established that copper readily oxides at ambient conditions, forming a passivating oxide layer. Experimental investigations spanning two decades have shown that in addition to the anticipated step ...

An Alternative Mechanistic Paradigm for the Electrochemical C‐Terminal Decarboxylation of Peptides
ChemElectroChem, EarlyView.Chemoselectivity in electrochemical oxidations is largely influenced by oxidation potential which represents a challenge for selectively oxidizing higher potential functional groups in complex substrates. Herein, a molecular binding strategy that selectively oxidizes the C‐terminal acid of a model peptide containing an electron‐rich tyrosine residue by
