Acid‐Catalyzed Rearrangement Reaction for Single‐Molecule Junction Formation

Chemistry – A European Journal, EarlyView.
Hydrazobenzenes cannot form single‐molecule devices with gold electrodes in a nonpolar solvent, but with the addition of trifluoroacetic acid, robust single‐molecule junctions are created. Hydrazobenzenes likely undergo rearrangement reactions to form benzidines, which are then attached to gold contacts by dative NH2→Au interactions for junction ...

Synergistic Action of Ascorbic Acid and Readily Accessible NHC^N Ligands for the Oxidation of Gold(I) With Electron‐Rich Aryldiazonium Salts

Chemistry – A European Journal, EarlyView.
The synergic action of ascorbic acid and NHC^N ligands enables Au(I) oxidation with electron‐rich aryldiazonium salts. ABSTRACT The synergistic action of ascorbic acid and NHC^N ligands enables the challenging oxidation of Au(I) with electron‐rich aryldiazonium salts in the absence of a cocatalyst and/or irradiation. EPR, NMR, and x‐ray analyses reveal

Diastereoselective Copper‐Catalyzed Defluorosilylation of Pentafluoroethyl Alkenes to Access Polyfluorinated Allylsilanes

Chinese Journal of Chemistry, EarlyView.
Under copper(I) catalysis, pentafluoroethylated alkenes can undergo smooth defluorosilylation to generate novel polyfluorinated products. The reaction exhibits high levels of diastereoselectivities for obtaining multisubstituted allylsilanes with control of the double bond geometry.

Post‐Synthetic Bimetallic Assembly of 2D CoFe‐MOF Composite as an Electrocatalyst for the Oxygen Evolution Reaction

CleanMat, EarlyView.
Post‐synthetic bimetallic assembly constructs a 2D CoFe‐MOF composite. DFT confirms Fe→O→Co synergy optimizes the OER pathway (ΔGmax = 1.67 eV), leading to ultralow overpotential (290 mV) and robust stability. ABSTRACT Metal‐organic frameworks (MOFs) are promising oxygen evolution reaction (OER) electrocatalysts, yet their commercial viability is ...

Identification and Characterization of the Designer Opioid N‐Pyrrolidino Fluetonitazene in Nasal Spray

Drug Testing and Analysis, EarlyView.
N‐Pyrrolidino fluetonitazene, a synthetic opioid, was identified and characterized in a nasal spray using GC‐MS, LC‐QTOF‐MS, NMR and FT‐IR. ABSTRACT Detection of drugs in non‐biological samples serves as a fundamental basis for identifying emerging trends in the field of new psychoactive substances and provides valuable information for optimizing ...

Phase I Metabolism of Novel Phencyclidine Derivative 3‐Cl‐PCP: In Vitro Studies With Pooled Human Liver Microsomes and Investigation of a Post‐Mortem Case

Drug Testing and Analysis, EarlyView.
A fatal 3‐chloro‐phencyclidine (3‐Cl‐PCP) intoxication was investigated by analyzing postmortem samples and a pooled human liver microsomes assay. Tentative metabolite identification was performed by liquid chromatography‐quadrupole time‐of‐flight mass spectrometry (LC‐QTOF‐MS). Seven phase I metabolites were identified.

Investigations Into the Metabolism and Elimination of Flmodafinil and Fladrafinil for Sports Drug Testing Purposes

Drug Testing and Analysis, EarlyView.
This article investigates the metabolism and elimination of flmodafinil and fladrafinil, two fluorinated analogs of modafinil and adrafinil listed as S6 stimulants by the World Anti‐Doping Agency. After single‐dose administration to six volunteers, the compounds and their main metabolites were studied in urine and blood.
