Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Inclusion Complexations of Levamisole and Cocaine With Molecular Baskets. Fluorescence Displacement Assay for Detection of Cocaine and Its Adulterant Levamisole in Aqueous Media

Chemistry – A European Journal, EarlyView.
Levamisole is a common adulterant found in street‐distributed cocaine. Molecular baskets have been shown to form stable inclusion complexes with both substances. While levamisole inserts its benzene into the basket's cavity, cocaine utilizes its bicyclic ring for encapsulation.

A Stable Isopterin Mimic of a Potent Bacterial Stimulant of T Cells

Chemistry – A European Journal, EarlyView.
A microbial metabolite covalently binds immunological protein MR1 to potently activate specific lymphocytes called MAIT cells, but it is too unstable for biological applications. Here, using synthesis, assays, protein crystallography, and computer modelling, we report a water‐stable analogue that activates reporter cells expressing the MAIT T cell ...

Photocatalytic N-Formylation of CO₂ with Amines Catalyzed by Diethyltriamine Pentaacetic Acid

C
In the present work, inexpensive and commercially available diethyltriamine pentaacetic acid (DTPA) was used as an initiator to catalyze the N-formylation reaction of CO2 with amines via the construction of C-N bonds in the presence of xanthone as the ...

Redox‐Tuned Oxycarbamates Enable Divergent C─N and C─C Functionalization of Indolizines Under Photoredox Catalysis With Green Light

Chemistry – A European Journal, EarlyView.
Nonafluoromesitylsulfonyl (Nms)‐substituted oxycarbamates are introduced as redox‐lowered radical precursors for green‐light photoredox synthesis. Selective N─O bond cleavage generates amidyl radicals that directly aminate indolizines in DMF, whereas DMSO promotes 1,2‐hydrogen atom transfer (HAT) to α‐amino carbon‐centered radicals and C─C bond ...
